For this laboratory work, 24 strips of the universal chemical indicator were used, which allows us to determine the medium of solutions. The mechanism of action of such indicators is based on chemical interaction with the substrate with the subsequent change of the stripe color. This change and the pH scale provide preliminary data on how acidic or alkaline the medium is. Although we cannot get the exact pH value, but thanks to the scale from below, it is possible to estimate the interval at least.
