A. Ionization constant

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-

Ka = \frac{[H+][CH3COO-]}{[CH3COOH]}

Since this process results in the formation of ions, Ka is also referred to as the ionisation constant.

What force in liquids causes surface tension? covalent forces intermolecular forces intramolecular forces ionic forces.
artcher [175]

Answer:

Intermolecular forces

Explanation:

Intermolecular forces cause surface tension.

Source info:
"Surface tension, capillary action, and viscosity are unique properties of liquids that depend on the nature of intermolecular interactions."
