Answer:
The reaction that happens when an acid, such as HCl , is mixed with a base, such as NaOH :
HCl(aq)+NaOH(aq)→NaCl(aq)+H2O(l)
When an acid and a base are combined, water and a salt are the products. Salts are ionic compounds containing a positive ion other than H+ and a negative ion other than the hydroxide ion, OH− . Double displacement reactions of this type are called neutralization reactions. We can write an expanded version of this equation, with aqueous substances written in their longer form:
H+(aq)+Cl−(aq)+Na+(aq)+OH−(aq)→Na+(aq)+Cl−(aq)+H2O(l)
After removing the spectator ions, we get the net ionic equation:
H+(aq)+OH−(aq)→H2O(l)
When a strong acid and a strong base are combined in the proper amounts—when [H+] equals [OH− ]\)—a neutral solution results in which pH = 7. The acid and base have neutralized each other, and the acidic and basic properties are no longer present.
Salt solutions do not always have a pH of 7, however. Through a process known as hydrolysis, the ions produced when an acid and base combine may react with the water molecules to produce a solution that is slightly acidic or basic. As a general concept, if a strong acid is mixed with a weak base, the resulting solution will be slightly acidic. If a strong base is mixed with a weak acid, the solution will be slightly basic
