Web4. a) Calculate the pH of a solution that is 0.60 M HNO2 and 0.40 M NaNO2. This is a buffer: we have a weak acid, HNO2, and its conjugate base, NO2 [acid] [base] pH = pKa + log (0.60 M) (0.40 M) pH = -log(4.5 x 10-4 ) + log pH = 3.35 + log(0.67) = 3.35 + (-0.18) = 3.17 b) Calculate the pH after 0.01 mol NaOH is added to 500.0 mL of the solution in part A. WebpH: The measure of acidity of a solution or mixture. The scale of pH ranges from 0 to 14 where everything between 0 and 7 is acidic and everything between 7 and 14 is basic.

WebCalculate the pH of a mixture containing 50 ml of 0.1 M NaH2PO4 and 150 ml of 0.1 M Na2HPO4. How many ml of 0.1 M H3PO4 should be added to the above buffer to lower the pH by 1 unit? This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. WebNow the mixture will acts as a salt CH3COO-Na+ of week acid CH3COOH and strong base NaOH. Then pH is 7 + 0.5* (pKa+ logX) here X is concentration of salt. We known that pKa of CH3COOH is 4.75 Given concentration of acid is 0.1M and base is 0.1 M Now both are equal volumes and concentrations. Let's assume conc Continue Reading 29 Rajkumar Subbiah WebQuestion: Calculate the pH of a mixture containing 50 mL of 0.1M NaH2PO4 and 150 mL of0.1M Na2HPO4.
