how find ph values
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 = -log_{10}[H^{+}]
pOH is calculated using the following formula: pOH = -log_{10}[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 H_{2}SO_{4}
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 = -log_{10}[H^{+}] pH = -log_{10}[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 = -log_{10}[OH^{-}]pOH = -log_{10}[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
