A) 2:2
B) 1:1
C) 1:2
D) 2:1
Correct Answer: C
Solution :
\[{{K}_{2}}{{S}_{2}}{{O}_{8}}(aq)+2KI(aq)\xrightarrow{{}}2{{K}_{2}}S{{O}_{4}}(aq)+{{I}_{2}}(aq)\]In this reaction one mole of \[{{K}_{2}}{{S}_{2}}{{O}_{8}}\]reacts with 2 moles of KI, hence the stoichiometry of this reaction is 1: 2.You need to login to perform this action.
