pH and pOH are both logarithmic scales measuring the acidity (or basicness) of a solution. pH is based on the amount of H+ (hydrogen ions), and pOH is based on the amount of OH- (hydroxide ions) in the solution.
You can calculate pH if you know the H+ activity: pH = - log10 (H+)
pOH is calculated the same way, except with OH- instead of the H+ ions.
pOH is also equal to 14 - pH. This is because the pH and pOH scales go from 0 to 14.
A solution that is very acidic will have a low pH number and a high pOH number.
Conversely, a very basic solution will have a low pOH and a high pH.
Water is a neutral solution and has a pH and pOH of 7, which is in the middle.

What can be used instead of phenolphthalein to measure pH?
Other pH indicators like bromothymol blue, methyl red, or universal indicator can be used as alternatives to phenolphthalein for measuring pH. Additionally, pH meters can provide a more accurate and continuous measurement of pH compared to indicators.
How can you measure the pH of an unknown liquid?
You can measure the pH of an unknown liquid using a pH meter or pH test strips. Simply dip the pH meter or test strip into the liquid and observe the reading or color change, respectively. This will give you an indication of the pH level of the unknown liquid.
What are the two methods used to measure the pH?
The two main methods used to measure pH are using a pH meter, which measures the voltage of a solution and converts it to pH, and using pH indicator strips, which change color based on the pH of the solution they are dipped into.
How do you measure pH accurately in a solution?
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.
How do you measure the pH levels in a tank?
To measure pH levels in a tank, you can use a pH test kit or a digital pH meter. Collect a water sample from the tank, follow the instructions on the test kit or meter, and record the pH reading. Make sure to calibrate your equipment regularly for accurate measurements.
What does the pH of a dilution measure?
pH is a measure of the hydrogen ion (H+) activity in a solution.
How do you measure pH without a pH meter?
We can use a pH paper.

measure the pH of a liquid and possibly a solid
What is a true pH?
pH is a measure of acidity or alkalinity of a solution.
What is pH engineering?
The pH is a measure of the acidity/basicity of a solution.
How 1.5 pH equal bars?
You can't convert that - they measure completely different things. pH is a measure of acidity. Bar is a measure of pressure.
