6. Question & Answer
  • 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.
