Chemical reaction: HSO₄⁻(aq) ⇄ H⁺(aq) + SO₄²⁻(aq);
or HSO₄⁻(aq) + H₂O(l) ⇄ H₃O⁺(aq) + SO₄²⁻(aq)
Ka₂ = [H⁺]·[SO₄²⁻]/[HSO₄⁻]; Ka₂ = 1.0·10⁻².
[H⁺] is equilibrium concentration of hydrogen cations.
[SO₄²⁻] is equilibrium concentration of sulfate anions.
[HSO₄⁻] is equilibrium concentration of hydrogensulfate(bisulfate) anions.
Explanation:
B more negative charges than positive charges
Light moves in a straight line except at surfaces between different transparent materials, where its path bends.
