Question

summarize the property of acids,based and salt

Answer 1

• In acid – base chemistry, salts are ionic compounds that result from the neutralization reaction of an acid and a base.
• 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.
• Acid salts contain a hydrolyzable proton in the cation, anion, or both; for instance, the salt ammonium bisulfate (NH4HSO4) contains an acidic proton in both the cation and the anion.
• To determine the acidity / alkalinity of a hydrolyzable anion, compare the Ka and Kbvalues for the ion; if Ka > Kb, the ion is acidic; if Kb > Ka, the ion is basic.
• Basic salts result from the neutralization of a strong base with a weak acid.
• Acid salts result from the neutralization of a strong acid with a weak base.
• For salts in which both cation and anion are capable of hydrolysis, compare Ka and Kbvalues to determine the solution ‘s resulting pH.
