That is, this equation goes to completion HCl ( aq) H ( aq) + Cl − ( aq) Thus, [ H +] = 1.2345 × 10 − 4. pH = − log ( 1.2345 × 10 − 4) = 3.90851 Exercise 7.14. 1 WebbWhen an acid is dissolved in water, the pH will be less than 7, while a base, or alkali, will have a pH greater than 7. A strong acid, such as hydrochloric acid , at concentration 1 mol dm −3 has a pH of 0, while a strong alkali like sodium hydroxide , at the same concentration, has a pH of 14.
Webb9 apr. 2024 · Strong Acids: Generally, acids are substances with a pH value of less than 7.0. The value goes on decreasing as the amount of H+ ion increases in the solution. Strong acids are the substances that release H+ ions rapidly or that are 100% ionizable in the solution. Thus, the strong acids have less pH value, nearly 0 to 1. WebbpH is zero for 1N solution of strong acid. pH is negative for concentrations 2N, 3N, ION of strong acids. At higher concentrations, in place of pH Hammett acidity functions are used. pH Scale pH Scale The concentration of hydronium ion is conveniently expressed on a logarithmic scale.
