The salt created when sodium hydroxide solution and hydrochloric acid combine is known as __________.

• A neutralization reaction is a type of chemical reaction between an acid and a base that results in the formation of  salt and water. 
• In this reaction, the hydrogen ions (H+) from the acid react with the hydroxide ions (OH^-) from the base to form water (H₂O). The remaining ions combine to form a salt.
• In the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) sodium chloride salt and water is formed. It can be represented by the following reaction:

                   HCl + NaOH → NaCl + H₂O
