Answer» COMMERCIAL LABELLING OF H2O2 AS ‘X’ VOLUME : Commercially H2O2 labelled as 'X' volume H2O2 (at P=1 ATM and T=273 K)Where 'X' may be 10V, 20V, 30V, 40 V etc. Here 'X' Volume H2O2 means that 1ml of such SOLUTION of hydrogen peroxide on decomposition produce 'X' ml of oxygen (at P=1 ATM and T=273 K).For example 10 Volume H2O2 means that 1ml of such solution of hydrogen peroxide on decomposition produce '10' ml of oxygen (at P=1 ATM and T=273 K).W/V % or PERCENTAGE STRENGTH OF H2O2SOLUTION: The amount of H2O2 in gram present in 100 ml of aqueous solution of H2O2. Called (w/v) or percentage strength.Illustration: taken 10 V (VOL) H2O2: |
