Using this ratio, we could calculate how many moles of Al are needed to fully react with a certain amount of Fe 2 O 3 , or vice versa. In general, mole ratios can be used to convert between amounts of any two substances involved in a chemical reaction.
21 lip 2020 · To calculate pH, first convert concentration to molarity. The easiest way to perform the calculation on a scientific calculator is to enter the hydrogen ion concentrations, press the log key ( not the ln key, which is natural logarithm), and then take the negative of the value.
This quiz helps you practice calculating pH and pOH from hydrogen ion (H+) and hydroxide ion (OH–) concentrations and vice versa.
30 lis 2018 · This downloadable PDF worksheet is for students to practice calculating pH and pOH values from concentration values of H + and OH-ions. Useful relationships: pH = -log[H + ] pOH = -log[OH - ] k water = 1 x 10 -14 = [H + ][OH - ] pH + pOH = 14
