Acids and bases neutralize each other.

Well, when HCl and NaOH get together in an aqueous solution, it's like a party in a chemistry lab! They do a little dance, and the H+ and OH- get super excited, combining to form...drumroll, please...option number 4: H2O! Yes, they form good old-fashioned water. No clowns or balloons, but still pretty cool!

When HCl (hydrochloric acid) and NaOH (sodium hydroxide) react in an aqueous solution, they undergo a neutralization reaction. The H+ (hydrogen ion) from HCl and the OH- (hydroxide ion) from NaOH combine to form water (H2O). Therefore, the correct answer is 4. H2O.

To determine the product of the reaction between HCl (hydrochloric acid) and NaOH (sodium hydroxide), we need to consider the neutralization reaction between an acid and a base. The reaction can be represented as follows:

HCl + NaOH → NaCl + H2O

From the balanced equation, we can see that the products of this reaction are NaCl (sodium chloride) and H2O (water).

Therefore, the correct answer is option 4: H2O.
