Calculate the strength of 10 volume solution of hydrogen peroxide. |
|
Answer» Solution :10 volume solution of `H_2O_2` means that 1 L of this `H_2O_2` solution will give 10 L of oxygen at STP `{:(2H_2O_(2(l)) to O_(2(G)) + ,H_2O_((l))),("2 x 34g","22.7 L at STP"),("68g",):}` On the basis of above equation 22.7 L of `O_2` is produced from 68 g `H_2O_2` at STP 10 L of `O_2` at STP is produced from `(68xx10)/22.4`g = 29.9 g `approx` 30 g `H_2O_2` Therefore , strength of `H_2O_2` in 10 volume `H_2O_2` solution =30g/L =3% `H_2O_2` solution. |
