Question

What type of ion does the substance give off if it turns the pH paper blue?

Answer 1

Alkaline

Step-by-step explanation:

In an alkaline solution, red litmus paper turns blue. When an alkaline compound dissolves in water, it produces hydroxide ions, which cause the solution to become alkaline.

Answer 2

The alkaline solution that turns the ph paper to blue and it produces hydrogen ions.

Step-by-step explanation:

• pH is defined as a measure of acid or alkaline level in the water and it indicates the amount of hydrogen molecules in the water.
• pH value ranges from [0-14], for acidic components pH<7 and base pH>7 and for neutral pH=7.
• Litmus paper measures the pH values and for acid the color of litmus paper changes from blue to red.
• For base solutions, the color changes from red to blue.
• Alkaline solutions change the pH value from red to blue, when it is dissolved in water.
