Hi
pH is a measure of the hydrogen ion concentration, [H+]
pOH is a measure of the hydroxide ion concentration, [OH-]
pH is calculated using the following formula: pH = -log10[H+]
pOH is calculated using the following formula: pOH = -log10[OH-]
Find the pH of a 0.2mol L-1 (0.2M) solution of HCl
Find the pOH of a 0.1mol L- (0.1M) solution of NaOH
Find the pH of a 0.2 mol L-1 (0.2M) solution of H2SO4
Find the pOH of a 0.1mol L-1 (0.1M) solution of Ba(OH)2
Hydrogen ion concentration, [H+], can be calculated using the following formula: [H+] = 10-pH
Hydroxide ion concentration, [OH-], can be calculated using the following formula: [OH-] = 10-pOH
Find the [H+] of a nitric acid solution with a pH of 3.0pH= 3.0 [H+] = 10-pH [H+] = 10-3.0 = 0.001mol L-1
You can check this answer by using the calculated value [H+] in the equation for pH to make sure you arrive at the original pHpH = -log10[H+] pH = -log10[0.001] = 3We get the same value for pH using the calculated value for [H+], so the calculated value for [H+] is correct.
Find the [OH-] of a sodium hydroxide solution with a pOH of 1pOH = 1 [OH-] = 10-pOH [OH-] = 10-1 = 0.1 mol L-1
You can check this answer by using the calculated value [OH-] in the equation for pOH to make sure you arrive at the original pOHpOH = -log10[OH-]pOH = -log10[0.1] = 1We get the same value for pOH using the calculated value for [OH-], so the calculated value for [OH-] is correct.
Find the pH of a solution of sodium hydroxide that has a pOH of 2
pH = 14 - pOHpH = 14 - 2 = 12
Find the pOH of a solution of hydrochloric acid that has a pH of 3.4
pOH = 14 - pHpOH = 14 - 3.4 = 10.6
Find the [H+] in a solution of sodium hydroxide that has a pOH of 1
Find the [OH-] of a sulfuric acid solution with a pH of 3
Find the pH of 0.2mol L-1 sodium hydroxide
Find the pOH of 0.2mol L-1 sulfuric acid
