Question

1.] Write the balanced chemical equations for the following acid-base neutralization reactions; HCI+ KOH HNO,+NaOH H2SO4+ KOH 24pK, of Carbonic acid, HCO, is 6.36. If an aqueous solution of carbonic acid is prepared such that (HCOs] is at 0.1 M and M, [H,CO] is at a) What is the pH of the solution? (Show your calculations). b) What is the [H'] of the solution? (Show your calculations) What is the [OH1 of the solution? (Show your calculations). c) 3] Saline is a solution of 0.9% (w/v) in water. (mEq/L) What is the total concentration of ions in saline? Provide the answer in milliequivalents/L. Hint: First calculate the molarity of NaCI. Then, the concentration of each ion in mEq/L. Add them together to figure-out the total electrolyte (ion) concentration. (Show your calculations).
