Question

Carrie is conducting an experiment on a solution. the solution's initial pH is 3.2. then, as carrie gradually adds compound x into the solution, the pH increases to 9.8.

what is compound x ?

Answer 1

2 or more elements bonded together

Answer 2

Strong base.

Step-by-step explanation:

pH may be defined as the negative logarithm of hydrogen ion concentration pH scale is used to measure the acidity or basicity of a substance. The acidic has pH less than seven where as base has a pH above seven.

Acid has the ability to release hydrogen ions and base releases hydroxyl ions in the solution. The initial pH of solution is 3.2, this indicates the solution is highly acidic. Carrie adds the substance X in the solution that increase the pH solution to 9.8, this means carry has added a base in the solution. The base release hydroxyl ions and increase the pH of the solution. The substance x might be a strong base.

Thus, the answer is strong base.
