Oct 7, 2004 · Has anyone raised Chemistry high enough to process the 300 ql alien mutated biomaterial? Trying to decide whether to give it a try. So far I've just been processing the pristine as the requirements are a lot lower (4x vs 7x).

The formula to calculate pH is: pH = -log[H+] The brackets refer to molarity, M. Molarity is given in units of moles per liter of solution. In a chemistry problem, you may be given concentration in other units. To calculate pH, first convert concentration to molarity. The easiest way to perform the calculation on a scientific calculator is to ente...
Sometimes you aren’t given the hydrogen ion concentration, so you have to figure it out from the chemical reaction or concentration of the reactants or products. If you have a strong acid, this is easy because strong acids completely dissociateinto their ions. In other words, the hydrogen ion concentration is the same as the acid concentration.
You can rearrange the pH equation to find hydrogen ion concentration [H+] from pH: pH = -log10[H+] [H+] = 10-pH
pH stands for “power of hydrogen” because the strength of an acid depends on the amount of hydrogen ion (H+) it releases in aqueous (water-based) solutions. In a way, water acts as both an acid and a base because it dissociates to produce a hydrogen ion and a hydroxide ion: H2O ↔ H+ + OH– Kw is the dissociation constant of water. Kw = [H+][OH–] = 1...
Avoid common pitfalls when calculating pH: 1. Use the correct number of significant figures. In chemistry, using the wrong number of digits may be counted as an incorrect answer, even if you set up the problem correctly. 2. Expect an answer between 0 and 14. Values slightly less than 0 and greater than 14 may occur, but you’ll never see a pH of -23...
