Question

A current of 3.40 a is passed through a pb(no3)2 solution for 1.60h

Option 1: Calculate charge
Option 2: Determine concentration
Option 3: Identify the electrochemical reaction
Option 4: Analyze current density

Answer 1

The total charge passed through a Pb(NO3)2 solution when a current of 3.40 A is applied for 1.60 hours is calculated using the formula Q = I × t, resulting in a charge of 19584 coulombs.

Step-by-step explanation:

The question involves a process of electrolysis, where an electric current is used to drive a non-spontaneous chemical reaction. In this case, the reaction is occurring in a Pb(NO3)2 solution. The task is to calculate the charge that passes through the solution when a current of 3.40 A is applied for 1.60 hours.

To find the charge, we use the formula Q = I × t, where Q is the charge in coulombs, I is the current in amperes, and t is the time in seconds.

1. First, convert the time from hours to seconds: 1.60 hours × 3600 seconds/hour = 5760 seconds.
2. Then, multiply the current by the time: 3.40 A × 5760 s = 19584 C.

The total charge passed through the Pb(NO3)2 solution is 19584 coulombs.
