Question

How does the pH of the solution on the right compare with that of the solution on the left?

1) The pH of the solution on the right is higher than that of the solution on the left
2) The pH of the solution on the right is lower than that of the solution on the left
3) The pH of the solution on the right is the same as that of the solution on the left
4) Cannot be determined from the given information

Answer 1

The pH of the solution on the right is higher than that of the solution on the left. Option 1

The pH scale, basic or alkaline solutions have a higher pH than acidic solutions. The pH scale is a logarithmic scale that measures the concentration of hydrogen ions in a solution. The scale ranges from 0 to 14 The higher the pH value, the more basic or alkaline the solution is. It's important to note that each unit change on the pH scale represents a tenfold change in the concentration of hydrogen ions.

We can see that there are more hydroxide ions on the left making that solution have a higher pH because it is basic in nature.
