Question

When a substance has a _____ pH, it has _____ hydrogen ions for a given volume. high; less low; less low; more high; more

Answer 1

Answer:

high less & low more

Explanation:

pH measures the quantity of hydrogen ions in a solution of a given volume, if pH is a low number, the amount of hydrogen atoms will increase, and if the pH is high, the amount of hydrogen atoms will decrease. So both high & less, and low & more are correct answers.

Answer 2

Answer:

When a substance has a high less pH, it has low more hydrogen ions for a given volume.

Explanation:

The pH, or Hydrogen Potential, is the scale that measures the degree of acidity or alkalinity of a substance, which can vary from 0 to 14.

PH is a characteristic of all substances, determined by the concentration of Hydrogen ions (H +). The lower the pH of a substance, the higher the concentration of H + ions and the lower the concentration of OH- ions. For this reason, we can affirm that when a substance has a high less pH, it has low more hydrogen ions for a given volume.

Knowing the pH of substances is a process that requires the help of a pH meter. Through this device it is possible to accurately measure the acidity of liquids.
