Write equations to illustrate the acid-base reaction when each of the following pairs of Brnsted acids and bases are combined: Acid Base a.HOCl H2O b.HClO4 NH3 c.H2O NH2 d.H2O OCl e.HC2O4 H2O

Which of the following substances are acids in terms of the Arrhenius concept? Which are bases? Show the acid or base character by using chemical equations. a P4O10 b Na2O c N2H4 d H2Te

. Consider 0.25 M solutions of the following salts: NaCl. RbOC1, KI, Ba(ClO4),, and NH4NO3. For each salt, indicate whether the solution is acidic, basic, or neutral.

Novocaine, C13H21O2N2Cl, is the salt of the base procaine and hydrochloric acid. The ionization constant for procaine is 7106. 15 a solution of novocaine acidic or basic? What are [H3O+], [OH-], and pH of a 2.0% solution by mass of novocaine, assuming that the density of the solution is 1.0 g/mL.

In each of the following chemical equations, identify the conjugate acid—base pairs. a. HF(aq)+H2O(l)F-(aq)+H3O+(aq)b. CN(aq)+H2O(l)HCN(aq)+OH(aq) c. HCO3-(aq)+H2O(l)H2CO3(aq)+OH-(aq)

. Water is the most common amphoteric substance, which means that, depending on the circumstances, water can behave either as an acid or as a base. Using HF as an example of an acid and NH3 as an example of a base, write equations for these substances reacting with water, in which water behaves as a base and as an acid, respectively.

You are asked for the H+ concentration in a solution of NaOH(aq). Because sodium hydroxide is a strong base, can we say there is no H+. since having H+ would imply that the solution is acidic?
