Product Details

Hydrion B test papers cover the odd PH range 1-3-5-7-9-11. Hydrion papers work best with buffered solutions. 15ft roll. The color changes are sharp and follow the natural spectral changes known to most chemists. Universal Indicator and Hydrion Papers are blends of different indicators that exhibits several smooth color changes over a wide range of pH values.

pH is a measure of acidity and alkalinity. The pH scale goes from 0 to 14. At pH 7, the halfway point, there is a balance between acidity and alkalinity, the solution is neutral. The pH of a substance is a measure of its acidity just as a degree is a measure of temperature. A specific pH value tells the exact acidity. If the solution has excess acid, the balance is shifted so the scale reads a number lower than 7. (i.e. the greater the acid strength the lower the pH value) Similarly, a solution that is alkaline has a pH that is higher than 7 and the higher the alkali strength the higher the pH value (up to 14).

Each unit on the pH scale actually represents a 10 fold difference in acid activity. Thus pH 4 is ten times as acidic a pH 5 solution. A pH 3 solution in turn has 10 times more acid than a pH 4 solution and 100 times the acid of the pH 5 solution.

The pH scale of 0 to 14 is derived from the chemical properties of water. The pH scale cannot be used with other solvents such as alcohol, oils and other non-aqueous systems.
