Question

Cr(OH)2+H2SO4(конц)=?

Answer 1

2Cr(OH)2 + 4H2SO4 = SO2 + Cr2(SO4)3 + 6H2O

Answer 2

The balanced chemical equation for the reaction between Cr(OH)2 and H2SO4 (concentrated sulfuric acid) can be represented as follows:

Cr(OH)2 + H2SO4 -> Cr(SO4)2 + 2H2O

In this reaction, Cr(OH)2 reacts with H2SO4 to produce Cr(SO4)2 (chromium sulfate) and water (H2O).
