2. Neutralization (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Neutralization_(chemistry)

   When a strong acid is neutralized by a strong base there are no excess hydrogen ions left in the solution. The solution is said to be neutral as it is neither acidic nor alkaline. The pH of such a solution is close to a value of 7; the exact pH value is dependent on the temperature of the solution. Neutralization is an exothermic reaction.

3. Piranha solution - Wikipedia

   en.wikipedia.org/wiki/Piranha_solution

   Molecular models of the different molecules active in Piranha solution: peroxysulfuric acid (H 2 SO 5) and hydrogen peroxide (H 2 O 2). Piranha solution, also known as piranha etch, is a mixture of sulfuric acid (H 2 SO 4) and hydrogen peroxide (H 2 O 2). The resulting mixture is used to clean organic residues off substrates, for example ...

4. Brake fluid - Wikipedia

   en.wikipedia.org/wiki/Brake_fluid

   The brake fluid in the tubes, in turn, pressurizes the brake slave cylinders, which are on each wheel. [22] [23] The slave cylinder pistons press down the brake pads. They encompass and compress the brake disk, and the rotation of the wheels slows down. In addition to transmitting pressure, brake fluid also keeps the brake system working optimally.

5. Buffer solution - Wikipedia

   en.wikipedia.org/wiki/Buffer_solution

   A buffer solution is a solution where the pH does not change significantly on dilution or if an acid or base is added at constant temperature. [1] Its pH changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical ...

6. Brake cleaner - Wikipedia

   en.wikipedia.org/wiki/Brake_cleaner

   Brake cleaner, often also called parts cleaner, is a mostly colorless cleaning agent, mainly used for cleaning the brake disks, the engine compartment and underfloor of motor vehicles. An important feature is that the brake cleaner leaves no residue after the solvents evaporate .

7. Acid value - Wikipedia

   en.wikipedia.org/wiki/Acid_value

   A liquid fat sample combined with neutralized 95% ethanol is titrated with standardized sodium hydroxide of 0.1 eq/L normality to a phenolphthalein endpoint. The volume and normality of the sodium hydroxide are used, along with the weight of the sample, to calculate the free fatty acid value. [3]

8. Dilatant - Wikipedia

   en.wikipedia.org/wiki/Dilatant

   Thus, the viscosity of a shear-thickening fluid is dependent on the shear rate. The presence of suspended particles often affects the viscosity of a solution. In fact, with the right particles, even a Newtonian fluid can exhibit non-Newtonian behavior. An example of this is cornstarch in water and is included in § Examples below.

9. Brake bleeding - Wikipedia

   en.wikipedia.org/wiki/Brake_bleeding

   Brake bleeding is the procedure performed on hydraulic brake systems whereby the brake lines (the pipes and hoses containing the brake fluid) are purged of any air bubbles. This is necessary because, while the brake fluid is an incompressible liquid , air bubbles are compressible gas and their presence in the brake system greatly reduces the ...
