Question

the relative amount of free hydrogen and hydroxyl ions in the water is measured by: the celsius scale the ph scale the calvin scale the richter scale a mixture of water and non dissolved material: solution suspension

Explanation:

The pH scale measures the relative amount of free hydrogen and hydroxyl ions in a solution. A suspension is a mixture of a liquid (like water) and non - dissolved material. A solution has dissolved solute. The Celsius scale measures temperature, the Calvin scale is also for temperature, and the Richter scale measures earthquake magnitude.

Answer:

1. B. the ph scale
2. B. suspension
