Predict the products of the following acid-base reactions, and predict whether the equilibrium lies to the left or to the right of the equation. Acidic salts formed form the reaction between a strong acid and a weak base. The fundamental concept of this theory is that when an acid and a base react with each other, the acid forms its conjugate base, and the base forms its conjugate acid by exchange of a proton (the hydrogen cation, or H +). Acid - Base Indicators: The most common method to get an idea about the pH of solution is to use an acid base indicator. Acid + Base ----> Salt + Water. Calculate the pH of a solution of a weak monoprotic weak acid or base, employing the "five-percent rule" to determine if the approximation 2-4 is justified. Compare pK_(a2) to pK_a ammonium bromide, 4. Since there are different degrees of ionization, there are different levels of weakness. Thus it is basic in nature.

Add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. This feature is not available right now. In a solution of a salt formed by the reaction of a weak acid and a weak base, to predict the pH, we must know both the Ka of the weak acid and the Kb of the weak base. That makes this salt, neutral. The weaker acid and weaker base are more stable (lower in potential energy) than the stronger acid and stronger base. When an amphiprotic molecule (or ion) reacts with a base, it acts as an acid. Apply the principles of acid-base chemistry to the design of molecules and Lewis acids with target functions. Acidic salts are salts whose aqueous solutions are are distinctly acidic in character. Acid-Base Reactions. But according to the HSAB principle, the Be 2+ ion is hard acid and is expected to show charge controlled bonding that results in more ionic nature for beryllium compounds. basicity of salt solutions by noting whether the corresponding acid and base are strong or weak. Briefly explain your results. 1M solutions of the following salts would be acidic, neutral, or basic: CaCl2, CuSO4, (NH4)2SO4, KClO4, KClO4, NaCN.
