During an electrolysis , the cations are discharged at cathode .This is called reduction
Name one divalent cation and one monovalent cation which will be discharged in preference to hydrogen ions .

Explanation

To solve the question, we need to identify one divalent cation and one monovalent cation that will be discharged at the cathode during electrolysis in preference to hydrogen ions. Here’s a step-by-step solution:

### Step 1: Understand the Concept of Electrolysis
During electrolysis, cations (positively charged ions) are attracted to the cathode (negative electrode) where they gain electrons, a process known as reduction.

**Hint:** Remember that reduction involves the gain of electrons.

### Step 2: Identify the Discharge Preference
