VOLUME STRENGTH

Relationship between volume strength of H_2O_2 aqueous solution and molarity depeds on pressre and temperature of O_2 (g) collected Example : "At1 atm ,273K," "Volume strength =11.2xxM" "At STP, " "Volume strength =11.35 x M" [Note : By default STP is taken for volume strength and calculationl. Find the relationship between volume strength and molarity at 300 K and 1 atm.

To a 25 mL of H_(2)O_(2) solution, excess of acidified solution of KI was added. The iodine liberated required 20 mL of 0.3 N Na_(2)S_(2)O_(3) solution. Calculate the volume strength of H_(2)O_2 solution. Strategy : Volume strength of H_(2)O_(2) solution is related to its normality by the following relation Volume strength (V)=5.6xx"Normality" (N) where, Normality =((meq)H_(2)O_(2))/V_(mL) According to the law of equivalence (meq)_(Na_(2)S_(2)O_(3))=(meq)_(I_(2))=(meq)_(H_(2)O_(2))
