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

Feb 13, 2016

$\text{Sulfuric acid + sodium hydroxide}$ $\rightarrow$ $\text{sodium sulfate + water}$

#### Explanation:

${H}_{2} S {O}_{4} \left(a q\right) + 2 N a O H \left(a q\right) \rightarrow 2 {H}_{2} O \left(l\right) + N {a}_{2} S {O}_{4} \left(a q\right)$

Because sulfuric acid is diprotic, it takes TWO equiv of sodium hydroxide for neutralization.

I could do the above reaction stepwise if I started with sodium bisulfate and added 1 equiv sodium hydroxide:

$N a H S {O}_{4} \left(a q\right) + N a O H \left(a q\right) \rightarrow {H}_{2} O \left(l\right) + N {a}_{2} S {O}_{4} \left(a q\right)$

Is is clear what I am doing here?
