Formula for find ph value |
| Answer» pH FormulapH\xa0is a measure of the amount of activity of hydrogen ions (H+) in a solution and thus its alkalinity or acidity. Although a pH value is unitless, it is not a random scale; the number rises from a description grounded on the activity of hydrogen ions in the solution.\xa0pH is described as\xa0“the negative of the logarithm of the molar hydronium-ion concentration.”pH Formula\xa0is arithmetically articulated as\xa0\xa0The\xa0pH Formula\xa0can also be noted as\xa0\xa0pH ProblemsSolved numerical based on pH are provided under.Problem 1:\xa0Calculate the pH of human arterial blood in which the hydronium ion concentration is 4.0 ×× 10-8M.Answer:The concentration of hydronium ion is 4.0 × 10-8MThus, we can make use of the formula,pH = – log[4.0 × 10-8]pH = 7.40As the hydronium ion concentration is provided till two decimal places we can note the pH with two significant figures. | |
