WebCalculate the pH of 0.010 M HBr in 0.090 M KBr. actually i solved in two different ways because in the first way WHICH I THINK I'M DOING RIGHT BUT HAVE WRONG ANSWER, so i tried the other way WHICH I THINK I'M DOING WRONG AND I DON'T KNOW WHY THATS THE SOLUTION BUT I GET THE RIGHT ANSWER..... (the book provides only the answer: 2.08) … WebNov 14, 2024 · For every mole of HBr, there will be 1 mole of H +, so the concentration of H + will be the same as the concentration of HBr. Therefore, [H +] = 0.025 M. pH is calculated by the formula. pH = - log [H + ] To solve the problem, enter the concentration of the hydrogen ion. pH = - log (0.025)
