Use a blue/ red litmus paper. When either turns red, it's acidic and blue is alkali.
You can measure the pH of an unknown colorless solution using a pH meter or pH paper. Simply dip the pH meter probe or pH paper into the solution and observe the reading or color change to determine the pH level of the 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.
Iodine does not have a pH since it is not an aqueous solution. pH is a measure of the concentration of hydrogen ions in a solution.
The concentration of hydroxide ions in a solution is related to the pH of the solution, but they are not exactly equivalent. The pH of a solution is a measure of the concentration of hydrogen ions, while the pOH is a measure of the concentration of hydroxide ions. The two values are related by the formula: pH + pOH = 14.
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.

The pH is a measure of the acidity/alkalinity of a solution.
A measure of the acidity of the solution
pH is a measure of the hydrogen ion (H+) activity in a solution.

pH is a measure of acidity or alkalinity of a solution.
The pH is a measure of the acidity/basicity of a solution.
pH paper and pH meter
The pH is a measure of the activity of the ion H+ in a solution.
pH is a measure of the acidity of the solution. It describes the concentration of H+ or H3O+ ions in a solution. pH= -log10[H+]. Therefore, the lower the pH, the higher the concentration of hydrogen atoms and the more acidic the solution.
