Question

Potassium dichromate in alkaline solution with $30$% $H_2{O}_2$ produces $K_{3}Cr{O}_8.$ How many peroxide linkages are found in the structure of $K_{3}Cr{O}_8$ ?

Answer 1

Potassium dichromate in alkaline solution with 30% $H_2{O}_2$ produces $K_{3}Cr{O}_8.$. The balanced chemical equation is as given below.
$K_{2}C{r}_2{O}_7+7H_2{O}_2+4KOH=2K_{3}Cr{O}_8+9H_{2}O$
Four peroxide linkages are found in the structure of $K_{3}Cr{O}_8$.
