If a substance is the limiting reactant, then it will be fully consumed by the time the reaction completes because <em />it is the reactant that reacts completely and the reaction cannot proceed further.
Answer:
it may be helium according to my knowledge
Given:
Volume of KOH = 53.0 mL
Concentration of KOH = 0.320 M
Volume of HNO3 = 28.0 mL
Concentration of HNO3 = 0.250 M
Balanced Equation:
KOH + HNO3 ===> KNO3 + H2O
0.320 0.250 0 0
H2O ===> H+ + OH-
Solve for the concentration of OH-
