Quick Recap — Titration Calculations

• $N_1V_1=N_2V_2$ (equivalents balance); Normality $=$ Molarity $\times$ n-factor.
• Molar-based: moles $=M\times V(L)$; use the reaction stoichiometry to relate the two solutions.
• $KMnO_4$ (acidic) n-factor $=5$; oxalic acid n-factor $=2$; $K_2Cr_2O_7$ n-factor $=6$.
• Percentage/strength from the volume of titrant at the end point.
