WebbpH of any acid can be calculated by using the following formula: pH= -log (H+) Here H+ refers to the concentration of H+ ions or the Hydronium ions. Here it can be clearly observed that 1 moles of sulphuric acid gives rise to 2 moles of H+ ions. Therefore, 0.01 moles of H2SO4 will give rise to 0.02 moles of H+ ions. WebbSince HCl is a strong acid, we will assume that it is 100 % ionized. We therefore have 0.001 mol H+ ions per liter. Now, the pH of a solution is given by the formula: pH = log 1/ [H+] which, in this case, is: log 1/0.001 =log 1000= 3.0. More answers below. hill climb racing latest versionWebbAll right, so the concentration of HCl in our original solution would be, we had 0.000844 moles. All right, divide that by liters. That was 0.0200 liters, right? 20 milliliters is equal to 0.0200 liters. And so we can do our calculation here. So we can take 0.000844, and we can divide that by 0.0200, and we get for our answer here 0.0422 molar. smart and final sales ad this week
