Acids and Bases - Calculating pH of a Strong Base

Acids and Bases - Calculating pH of a Strong Base KOH is a case of a solid base, which implies it separates into its particles in fluid arrangement. In spite of the fact that the pH of KOH or potassium hydroxide is incredibly high (normally extending from 10 to 13 in run of the mill arrangements), the specific worth relies upon the grouping of this solid base in water. In this way, its essential to realize how to play out the pH count. Solid Base pH Question What is the pH of a 0.05 M arrangement of Potassium Hydroxide? Arrangement Potassium Hydroxide or KOH, is a solid base and will separate totally in water to K and OH-. For each mole of KOH, there will be 1 mole of OH-, so the centralization of OH-will be equivalent to the grouping of KOH. Hence, [OH-] 0.05 M. Since the grouping of OH-is known, the pOH esteem is progressively helpful. pOH is determined by the equation pOH - log [OH-] Enter the fixation found previously pOH - log (0.05)pOH - (- 1.3)pOH 1.3 The incentive for pH is required and the connection among pH and pOH is given by pH pOH 14 pH 14 - pOHpH 14 - 1.3pH 12.7 Answer The pH of a 0.05 M arrangement of Potassium Hydroxide is 12.7.
