A1.25 m solution of the weak acid ha is 9.2% dissociated. what is the ph of the solution?

0.94 is the pH of the solution.

Explanation:

The equilibrium reaction for dissociation of (weak acid) is,

initially conc.         c                       0         0

At eqm.                                      

Concentration (c) = 1.25 M

Degree of dissociation = = 9.2% = 0.092

The pH of the solution is :

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
