The salt sodium sulfate, #Na_2SO_4# can be formed by a reaction between which two compounds?

Answer 1

#"Sulfuric acid + sodium hydroxide"# #rarr# #"sodium sulfate + water"#

#H_2SO_4(aq) + 2NaOH(aq) rarr 2H_2O(l)+Na_2SO_4(aq)#

Sulfuric acid requires TWO equivalents of sodium hydroxide to neutralize because it is diprotic.

If I added one equivalent of sodium hydroxide to sodium bisulfate first, I could carry out the above reaction step-by-step:

#NaHSO_4(aq) + NaOH(aq) rarr H_2O(l)+Na_2SO_4(aq)#

Is what I'm doing here clear?

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
