Calculate the pH of a solution made by adding 25.0 g of sodium formate, NaHCOO, to 400 ml of 0.64 M formic acid, нсоон. Answer: What is the pH of pure water at 25°C? Answer: When a small amount of acid is added to a non-buffered solution, there is a large change in pH. Calculate the pH when 22.2 ml of 0.0020 M HCl is added to 100.0 mL of pure water. Comment and hint in the general feedback Answer:
(10 pts) A solution is prepared by dissolving 1.239 grams of hydrochloric acid, HCI, in enough water to make 250.0 mL of solution. A 25.00 mL sample of this solution is diluted with water to a final volume of 100.0 mL. Now, you take 10.00 mL of that solution and dilute it to 100.00 mL What is the molarity of the final solution? (HCI 36.45 g/mol)
