Question

Write 2 separate balanced equations for the neutralization reactions of hydrochloric acid with sodium hydroxide and acetic acid with sodium hydroxide......i never get how to do that!

Answer 1

Remember this.
acid + base = salt + H2O.

I'll do the first one and leave the second for you.
HCl + NaOH ==> NaCl + HOH. Just pull the H and OH out and what's left is the salt.

HC2H3O2 + NaOH ==>
On HC2H3O2, it's the FIRST H that is the acid H, the H3, for example, is part of the rest of the formula. I prefer to write acetic acid as HAc where H stands for the acidic H and Ac stands for the rest of the molecule.

Answer 2

so that second one would end up being:
NaOH + CH3COOH--> Na+ CH3COO + H2O
....right?

Answer 3

exactly. Very good.

Answer 4

how many grams of sodium hydroxide is required to neutralize 73grams of hydrochloric acid and to form sodium chloride and water
