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 ...
