Problem- 50 ml if .15M NaNO was added to a sample containing gallium. Nitrate oxidized Ga(s) to Ga(aq). The resulting nitrous acid was titrated to the equivalence point with 27.82 mL of .1M NaOH. Determine the mass of Ga(s) in the sample
NO3 +3H+ + 2e- ï--> HNO2 + H2O
Ga3+ +3e- ï--> Ga(s)
HNO2ï--> H+ +NO2-
Give me complete explanations of above question thus I can get high score
