Q. Define the Normality of solutions?
Ans. Sometime normality is used to measure concentration. Normality (abbreviated N) is the number of gram-equivalent masses of solute in 1 liter of solution. A gram-equivalent mass is the mass of acid (or base) which can give one mole of hydrogen (or hydroxide) ions.
The number of d electrons in Fe +2 (atomic number of Fe= 26 ) is not equal to that of the: (1) p-electrons in Ne (At. No.= 10) (2) s-electrons in (At. No.= 12)
Overall reaction is H+ + I- +H2O2 -> H2O +HIO. If you wanted to increase the rate of the overall reaction, would it be better to increase the concentration of H+ or I-. Why?
