## Question:

Find the molarity of a HCl solution if 25.5mL of HCl is required to neutralize 0.375g of Na2CO3 as shown in the following equation:

2HCl(aq) + Na2CO3(aq) -> 2 NaCl(aq) + H2O(l) + CO2(l)

## Neutralization Reactions:

Chemical reactions can be classified based on the identity of the substances involved. An example of such a reaction is a neutralization reaction. Neutralization reactions always involve acid and base reacting to form water and salt.
