The ph of 0.02 m koh aq solution at 25°c is
WebbWe will calculate the pH of 25 mL of 0.1 M HCl titrated with 0.1 M NaOH. At each point in the titration curve, we will need to determine two quantities, the concentration of H + remaining in the solution, and the volume of the solution. From these, we can calculate the [H +] and, from that, the pH. 1. WebbpH is defined as the negative of the base-ten logarithm of the molar concentration of hydrogen ions present in the solution. The unit for the concentration of hydrogen ions is moles per liter. To determine pH, you can use this pH to H⁺ formula: pH = -log([H⁺]) Step by Step Solution to find pH of 0.002 M : Given that, H+ = 0.002 M

Assume … Webb14 okt. 2024 · The pH of 0.02 M is 1.4. Explanation: pH or pOH is the measure of acidity or alkalinity of a solution. pH is calculated by taking negative logarithm of hydrogen ion concentration. According to stoichiometry, 1 mole of gives 2 mole of . Thus 0.02 moles of gives = moles of . Putting in the values: Thus pH is 1.4. Learn more about pH. brainly.in ...
