Question

How does nitric acid reaction with sodium hydroxide?

Answer 1

`HNO_3(aq) + NaOH(aq) rarr NaNO_3(aq) + H_2O(l)`

Explanation:

Acid + base yields a salt and water, as the above reaction signifies.

Because it is 1:1 reaction (what do I mean here?), the quantity (the amount) of sodium hydroxide is precisely equal to the amount of nitric acid.

Moles of nitric acid: `680 xx 10^(-3) cancel(L)xx0.640*molcancel(L^(-1))` `=` `???` `mol`. I included the units in the calculation, because if a calculation makes sense dimensionally (and here it did, I required an answer in `mol`), it is a good indication that I have set up the problem correctly.
