Question

Write one chemical reaction for the prepartion of $D_2{O}_2$

Answer 1

Laboratory method for prepartion of $D_2{O}_2$ is:$K_2{S}_2{O}_2\left(s\right)+2D_{2}O\left(l\right)\to 2KDS{O}_4\left(aq\right)+D_2{O}_2\left(l\right)$

Here, peroxodisulphate $\left(K_2{S}_2{O}_8\right)$ on reaction with heavy water yields deterium peroxide $\left(D_2{O}_2\right)$.
