What proportions of sodium bisulfate and sodium sulfate should I mix to make a pH 4.50 buffer? Bisulfate ( H S O 4 − " style="position: relative;" tabindex="0" id="MathJax-Element-1-Frame" class="MathJax" H S O − 4 H S O 4 − ) has a pKa of 1.99. You can’t make a pH 4.50 buffer using the...

Aquated sodium, and sulfate ions… [math]Na_{2}SO_{4}(s) \stackrel{H_{2}O}\longrightarrow 2Na^{+} + SO_{4}^{2-}[/math] The sodium ion is likely present as its water solvate, i.e. [math][Na(OH_{2})_{6}]^{+}[/math] …we write [math]Na^{+}[/math] for short…sulfate would be similarly hydrated…

This is a typical ion exchange reaction. Here's the equation: Pb(NO3)2 + Na2SO4 ---> PbSO4 + 2NaNO3 Reaction happens because lead sulfate and sodium nitrite are more stable than lead nitrate and sodium sulfate.

It doesn’t react. It dissolves. Its solubility in water is very good, about 1 part Na₂SO₄ in 2 parts water at 33 ⁰C.
