HCHO disproportionates to HCOO⁻ and CH₃OH in the presence of OH⁻ (Cannizzaro's reaction). 2HCHO + OH⁻ HCOO⁻ + CH₃OH. If the equivalent weight of HCHO is E, then the value of E/10 is
Answer:
3.00
Solution:
In 2HCHO + OH⁻ HCOO⁻ + CH₃OH, one C goes 0 +2 (loses 2e) and the other 0 -2 (gains 2e): 2e⁻ transferred per 2 mol HCHO, so n-factor = 1. E = M/1 = 30/1 = 30. E/10 = 3. Ans: 3.
