This online quiz is intended to give you extra practice in calculating pH and pOH from hydrogen ion (H+) and hydroxide ion (OH-) concentrations and vice versa. Select your preferences below and click 'Start' to give it a try!
Calculate the pH of a solution prepared by adding 55.0 mL of a 0.120 M \(NaOH\) solution to 100.0 mL of a 0.0510 M solution of oxalic acid (\(HO_2CCO_2\)H), a diprotic acid (abbreviated as H2ox). Oxalic acid, the simplest dicarboxylic acid, is found in rhubarb and many other plants.
Solutions. Note: The significant figures in the concentration of [H+] or [OH -] is equal to the number of decimal places in the pH or pOH and vice versa. 1) What is the pH of a 0.0235 M HCl solution? pH = -log[H+] = -log(0.0235) = 1.629. 2) What is the pOH of a 0.0235 M HCl solution?
We will calculate the pH of the solutions using the following 3 steps for each problem. Step 1: What is left in solution? Step 2: What are the equilibrium concentrations of the species in solution?
15 kwi 2024 · Calculate the pH of a solution of a weak monoprotic weak acid or base, employing the "five-percent rule" to determine if the approximation 2-4 is justified. Predict whether an aqueous solution of a salt will be acidic or alkaline, and explain why by writing an appropriate equation.
