A solution is made by adding 52.0 mL of 0.230 - M acetic acid (Ka = 1.8 times10^-5) to 52.0 mL of 1.5 x10^-3M HCI. Calculate the pH of the solution. Calculate the acetate ion concentration.

A chemist titrates 230.0 mL of a 0.8865 M sodium hydroxide (NaOH) solution with 0.6960 M HBr solution at 25 °C. Calculate the pH at equivalence. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of HBr solution added. pH = X

A 25 Celsius aqueous solution is made by adding 2.31 liters of 0.348 M NaNO2 to 3.36 liters of 0.118 HNO2. The Ka of HNO2 is 4.7x10-4.  What is the pH of this resultant solution?

Calculate the pH of a solution made by mixing 200.0 mL of 0.64 M hydrocyanic acid (Ka = 4.9 × 10−10) with 150.0 mL of 0.87 M sodium cyanide solution.

Explain why H2S is a stronger acid than H,O. Select all that apply. Sulfur appears below oxygen in the periodic table. The S-H bond is stronger than the O-H bond. The S-H bond is weaker than the O-H bond. The statement is incorrect, the stronger acid is H20.
