The H means hydrogen, but noone save the inventor of the pH system truly knows what the p means.

The acronym pH stands for "potential of hydrogen." It is a measure of the acidity or alkalinity of a solution on a scale from 0 to 14, with 7 being neutral, below 7 acidic, and above 7 alkaline.
pH stands for "potential of hydrogen." It is a measure of the acidity or basicity of a solution, with values ranging from 0 to 14. A pH of 7 is considered neutral, below 7 is acidic, and above 7 is basic.
pH 1 is the most acidic, as it is closest to 0 on the pH scale. Lower pH values indicate higher acidity.
You can test the pH of a solution using pH strips, pH meters, or pH indicator solutions. With pH strips, you simply dip the strip into the solution and compare the color change to a pH color chart. pH meters provide a digital pH value by immersing the electrode into the solution. pH indicator solutions change color based on the pH of the solution, allowing for a visual estimation of pH.
To measure pH accurately in a solution, you can use a pH meter or pH strips. A pH meter provides a digital reading of the pH level, while pH strips change color based on the pH level of the solution. Simply dip the pH meter probe or pH strip into the solution and read the pH value indicated.
Acidic: pH less than 7 Neutral: pH of 7 Basic: pH greater than 7
