Hi I'm Stephan Moritz and I'm a commercial pilot. As you know there are many products that are in the automotive world that are born and bred with an aviation and aerospace history. Cilajet is one of those products. Much like you have GPS and plastics that came out of NASA and Boeing schools of thought and engineering; Cilajet has that same unique heritage. What's amazing for me to hear are the testimonials that continuously come into Cilajet. The customers on the automotive side experience every day environmental wear and tear on their vehicle, it's a need based product. They inevitably will have bird droppings, tree sap or water spots or mineral deposits that build up which typically are extremely difficult to get off the paint. OK, so here's a little bit of a personal testimonial that I have, you know I had seen it on the aircraft, I had a 2006 Silver Z4 and I had really wanted to put it to the test, it had gone through normal washes and exposure to snow and also the desert heat out in Southern California and what I had Cilajet do was treat half my vehicle, they treated the driver's side and did not treat the passenger side. After about a week I said ok, this looks interesting, I can see something happening. The first thing I saw was the driver’s side rim had no break dust on it and the passenger side rim, as most people know with BMW's with a high performance braking system, was coated in brake dust. I said, 'Wow, ok this is starting to live up to the hype, live up to that expectation'." After a couple of more weeks, that the dirt was building up on the untreated side significantly more than on the treated side, so much so to the point that people thought I was running a really funny chemistry experiment, which I was because the Cilajet had really bonded at a molecular level to the paint on the driver's side. After a wash, again, the difference was very clear. The treated side was nice smooth and clean, fresh, baby new all over again. The side that was untreated, unfortunately, wasn't so clean, was still gritty, grimy; the rims didn't look great at all. That's when I was sold. So one of the nicest things that I've experienced about the Cilajet is not only the joy owning vehicles with Cilajet on it, and the shine that it has and how great it looks and the no brake dust factor is when I go to sell my car. The resell value. I've done a couple of private party sales as well as trade-ins and returns at a dealership and most dealerships will always have some sort of reconditioning cost. My vehicle always appraises at excellent in the Kelly Blue Book world and there is no exterior or interior reconditioning that's ever necessary.
Part 1 of 2. For the HSC Chemistry syllabus dot-point: “Perform a first-hand investigation and solve problems using titrations including the preparation of standard solutions, and use available evidence to quantitatively and qualitatively describe the reaction between selected acids and bases”. This experiment is important because it is one of the most commonly chosen experiments for Prac Exams. Prac Exams could come any time throughout year 12 – but most of the time they occur as part of your trial HSC exams, and usually worth around 20% of total internal assessment. Therefore it is important to pay close attention to proper titration procedure and understand the underlying processes of neutralization reactions.
For this titration, our unknown was a solution of NaOH (the analyte) and our standard solution was oxalic acid (crystals in dihydrate form) – the titrant. Glassware was rinsed properly with either deionised water or with the solution it was to contain (conical flask, volumetric flask – water / pipette, burette – solution). A total of 1 ‘rough titre’ and 3 accurate titres were done. The average of the 3 accurate titres were recorded and used to finally calculate the concentration of the unknown NaOH. Our indicator was phenolphthalein due to its slightly basic endpoint (the titration was between a strong base and a weak acid, therefore the equivalence point would be slightly basic). Tip: If required to make your own standard solution, make sure you design your standard solution so that it was enough moles for you to do 3 titres.
For the HSC Chemistry syllabus dot-points: “Perform a first-hand investigation to prepare and test a natural indicator” and Solve problems by applying information about the colour changes of indicators to classify some household substances as acidic, neutral or basic”.
We crushed some red cabbage immersed in ethanol to extract the anthocyanin. This purple solution was applied to several household solutions varying in pH and the range of colours were analysed according to the known acidity / basicity of the solutions tested.
We make concentrated sulfuric acid from sodium metabisulfite, hydrochloric acid and an oxidant such as hydrogen peroxide or nitric acid.
Warning: The procedures in this video produce large quantities of toxic gases and deal with highly corrosive acids. All work must be performed in a fume hood with proper safety equipment. And all apparatus must be glass to withstand the acids.
Sodium metabisulfite upon reaction with acid will generate sulfur dioxide. This provides a convenient source of sulfur dioxide that is easier to handle than burning sulfur, but it is acceptable if you want to go that route. You'll just need to build a sophisticated gas capture and scrubbing system so the sulfur vapors and soot don't clog your tubes, poison your air and possibly burn down your workspace.
Sulfur dioxide is converted into sulfuric acid by reacting it with an oxidizer in water. In this case either hydrogen peroxide or nitric acid.
Industrially, sulfur dioxide is reacted with oxygen over a catalyst to make sulfur trioxide. This is cheaper but extremely difficult to do safely for the home chemist so the metabisulfite/oxidizer method is used instead.
You may use potassium metabisulfite instead of sodium metabisulfite. Both are used by home brewers to sterilize winemaking and beermaking mixtures. It's also used for homemade dyeing processes. Therefore it is very easy to obtain the metabisulfites without the need for expensive shipping fees or licenses.
The oxidizers must be present for this reaction to work. You cannot simply use water or you'll just make sulfurous acid which decomposes on heating and is useless for the reactions that sulfuric acid is intended for.
In future videos, we may show other methods of sulfuric acid production including sulfur trioxide based methods so please subscribe!
You CANNOT use a sulfate in place of a sulfite, they are chemically different and cannot be substituted.

Direct Conversion of Potassium Chloride to Potassium Chlorate by Electrolysis of a Hot Solution of Potassium Chloride
Display of two spectacular combustion phenomena: the "pulse jet," and a sheet of flame propagating through a closed space. In my humble opinion, probably the best quality video of this particular experiment on YouTube.
A chick and two guys have fun with a crazy chemistry experiment.
