What is another name for the acid dissociation constant?
2 answers:
Answer:
a. ionization constant
Explanation:
The acid dissociation constant is an indicative of the strength of an acid in solution i.e. extent to which it dissociates thereby releasing H+ ions. It is represented as Ka
For strong acids, Ka = 1 since they completely dissociate into the respective ions. Example is HCl
HCl → H+ + Cl- Ka = 1
For weak acids like acetic acid (CH3COOH) there is an equilibrium between the dissociated and undissociated ions
CH3COOH ↔ H+ + CH3COO-
Since this process results in the formation of ions, Ka is also referred to as the ionisation constant.

Answer:- Mole ratio of D to A is 4:3.
Explanations:- Mole ratio for a chemical reaction is the ratio of the coefficients.
The given generic chemical reaction is:
The numbers written in front of each chemical species in the chemical reaction are their moles. For the given generic chemical reaction the coefficient of A is 3 and that of B is 1. So, the mole ratio of A to B is 3:1.
Similarly if we want to write the mole ratio of C to D then it is 1:4.
We are asked to write the mole ratio of D to A. So, like the other ratios, the mole ratio of D to A is 4:3 as the coefficient of D is 4 and A is 3.
