If so would I need to change the ratio,or rxn conditions?

Thankyou kindly,
Have a nice day

You need freshly fused KHSO₄, so i'd suggest you make it yourself:


KOH + H₂SO₄ ^__> KHSO₄ + H₂O


I see no immediate reason why NaHSO₄ couldn't be substituted here.

KOH and H2SO4 often have small amounts of water present... KHSO4 likely also picks up water better than NaHSO4.

I'm not saying you're wrong or anything though.
