In Chapter 8, you learned that a neutralization reaction can be defined as the reaction of an acid and a … Those properties are outlined below: Aqueous solutions of acids are electrolytes, meaning that they conduct an electrical current. The pH should be greater than seven. When dissolved in water, they dissociate into individual hydrated ions that may or may not affect the pH of the solution. When salts dissolve in water, they dissociate into aqueous solutions of ions that may or may not affect the pH of a solution. View Predicting the qualitative acid-base properties of salts.pdf from CHEM 1040 at Auburn University. Salts, being strong electrolytes, dissociate completely in aqueous solution to produce the ions which they are composed of. For instance, in the reaction of hydrochloric acid (a strong acid) with ammonia (a weak base), water is formed, along with ammonium chloride. Get your answers by asking now. If you have the salt, this salt here that was formed from a weak acid and a strong base, these salts form basic solutions with pHs greater than seven. Basic salts contain the conjugate base of a weak acid, so when they dissolve in water, they react with water to yield a solution with pH greater than 7.0. Course Hero, Inc. Therefore, salt solutions can be acidic, basic or neutral. What will be the effect of the anion on the pH of water? Acid salts are the converse of basic salts; they are formed in the neutralization reaction between a strong acid and a weak base. In other words, aqueous solutions like NaCl, KCl, and NaNO 3 are neutral, or have a pH = 7. In acid – base chemistry, salts are ionic compounds that result from the neutralization reaction of an acid and a base. For example, the fourth compound breaks up like this. HONH3Br - salt from a strong acid (HBr) and a weak base (HONH2) - pH will be <7 (acidic) NH4CN - salt from a weak acid (HCN) and a weak base (NH3) - pH will depend on the Ka and Kb.
