High hydrogen ion concentration ph
WebBecause pH is defined as the negative logarithm of hydrogen ion concentration (pH = −log[H +]), these values of hydrogen ion concentration correspond to a pH range of 7.35 to 7.45. Acidosis is a downward shift in pH to less than 7.35, and alkalosis is an upward shift in pH to more than 7.45. Pure water is neutral. When an acid is dissolved in water, the pH will be less than 7 (25 °C). When a base, or specifically an alkali, is dissolved in water, the pH will be greater than 7. A solution of a strong acid, such as hydrochloric acid, at concentration 1 mol dm has a pH of 0. A solution of a strong alkali, such as sodium hydroxide, at concentration 1 mol dm , has a pH of 14. Thus, measure…
High hydrogen ion concentration ph
Did you know?
WebThe pH range does not have an upper nor lower bound, since as defined above, the pH is an indication of concentration of H +. For example, at a pH of zero the hydronium ion concentration is one molar, while at pH 14 the hydroxide ion concentration is one molar. WebThe hydrogen ion concentration decreases by a factor of 10, so the pH increases by 1 from 1.6 to 2.6. Question A solution of hydrochloric acid, with a concentration of 2 g/dm 3 , has a pH of 1.3.
