Question

An acidified solution of potassium chromate was layered with an equal volume of amyl alcohol. When it was shaken after the addition of $1 mL$ of $3 % H_{2} O_{2},$ a blue alcohol layer was obtained. The blue color is due to the formation of a chromium (VI) compound $' X'$ . What is the number of oxygen atoms bonded to chromium through only single bonds in a molecule of $X$ ?

Answer:

4.00

Solution:

$K_{2} {CrO}_{4} \overset{H^{+} / H_{2} O_{2}}{\to} \underset{(Deep Blue solution)}{{CrO}_{5}}$

No. of oxygen atom bonded with chromium with single bond is $(4)$ .

TestHub · Accepted Answer

K 2 CrO 4 → H + / H 2 O 2 CrO 5 ( Deep Blue solution ) No. of oxygen atom bonded with chromium with single bond is ( 4 ) .
