H_(2) A is a weak diprotic acid. If the pH of 0.1 M H_(2)A solution is 3 and concentration of A^(2-) is 10^(-12) at 25^(@)C. Select correct statement (s)
During the titration of a weak diprotic acid (H_(2)A) against a strong base (NaOH) , the pH of the solution half-way to the first equivalent point and that at the first equivalent point are given respectively by:
Determine the pH of the solution when hydrogen ion concentration is 1.0xx10^-5M .
Determine the pH of the solution when hydrogen ion concentration is 1.0xx10^-9M
The hydroxide ion concentration of a wine is 8xx10^(-11) M. What is the pH of the wine?
pH of 10^(-6) M HCl (aq.) is :
A 20.0 mL sample of a 0.20 M solution of the weak diprotic acid H_(2)A is titrated with 0.250 M NaOH. The concentration of solution at the second equivalent point is:
Subtract: 3l (l – 4 m + 5 n) from 4l ( 10 n – 3 m + 2 l )
For the reaction 2N_2O_5 to 4 NO_2 + O_2 rate and rate constant are 1.22 xx 10^(-4) and 3.4 xx 10^(-5)s^(-1) respectively then the concentration of N_2O_5 at that time will be
