For each of the following reactions, identify the reactant acting as the acid, the reactant acting as a base, and their respective conjugate bases and acids.
1. H2S+CN-=HS-+HCN
2.F +HSO- = HF +SO2-4

Calculate: select the worksheet tab. this tab you calculate the analyte concentration.  fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.)  record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes.  record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed
