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. WebbThis only time this becomes important is at very low (< 10-6 M) concentrations of acids or bases, when water will be the main source of H + and OH-. Example 1 - Finding the K a of a weak acid from the pH of its solution. A 0.10M solution of formic acid, HCOOH, has a pH = 2.38 at 25 o C. Calculate the K a of formic acid. 1.

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 ... Webb5. 300 ml of a 0.02 M NaOH solution are mixed with 200 ml of 10-2 M Ba(OH) 2 solution. Calculate the pH of the resulting solution. Both the bases are fully dissociated in solution. The number of moles of OH ... = 0.01 and since the final volume of the solution is 500 ml the solution results to be 0.02 M in OH-: pOH = - log 0,02 = 1,69 . pH =14 ...
WebbH2SO4 (aq)————→ 2H+ (aq) + (SO4)^2- (aq) 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 Substituting the value of H+ in the formula, pH=-log (0.02) which is equal to 1.698. Therefore pH of 0.01 moles of H2SO4 is 1.698 or 1.70.
