Predict the products of each reaction, and whether the solution at equilibrium will be acidic, basic, or neutral. At equilibrium the solution is...? reaction O acidic N,0,(6) + 3H,0(1) → 0 O basic O neutral O acidic co,(k) + H,0(1) O basic O neutral O acidic Na, 0 (s) + H,0(1) O basic O neutral

A 0.75 M solution of a certain weak base has a pH of 11.60. What is the K, for this weak base? O 3.6 x 104 O 2.4 x 10-7 O 3.0 x 10 4 O 7.2 x 10 10 O 2.1 x 10-5

I Review | Constants | Periodic Table Learning Goal: Part A To calculate pH and use it as a measure of acidity. The pH expresses the molar concentration of hydronium ions in an aqueous solution on a logarithmic scale: What is the pH of an aqueous solution with [H30+] =2x10-14 M? Express the pH numerically using one decimal place. pH = -log[H3O+] • View Available Hint(s) [H3O+] = 10-pH As pH decreases, acidity increases. As pH increases, acidity decreases. • Acidic solution: pH 7 pH = Submit Part B Carbonated cola is more acidic than coffee or even orange juice because cola contains phosphoric acid. What is the molar concentration of H3O+ in a cola that has a pH of 3.120? Express your answer with the appropriate units. • View Available Hint(s) [H3O*] = Value Units Submit
