The addition of 0.1M HCl and 0.1M NaOH both of equal amounts is considered to be a neutralization reaction. A neutralization reaction is basically a double replacement reaction participated by both an acid and a base. In this case, the NaOH is the base while the HCl is the acid. The reaction will yield the following products: Water (H20) and aqueous Sodium Chloride (NaCl). Neutralization reactions always yield a salt and water as the end products.
