An aqueous solution of an acid conducts electricity. This is because
It contains hydrogen ion
Acids ionise in aqueous solution to release hydrogen ions (H+). It is the presence and movement of these free ions that allows the solution to conduct an electric current.
When electricity is passed through an aqueous solution of sodium chloride, it decomposes to form
You are given three metals 'X', 'Y' and 'Z'. Metal 'X' is found to react with an aqueous solution of both YSO 4and ZSO 4whereas metal 'Z' is found to react only with aqueous solution of YSO 4. Based on these observations, select the correct statement from the following.
The mobility of a divalent cation in water is 8 × 10-8 m2 V-1 s-1. The effective radius of the ion is (viscosity of water = 1 cP : c = 1.6 × 10-19 C)
The electrical double layer model among the following that consists of both fixed and diffuse layers is
