pH Indicator (Solid)

A pH indicator is a halochromic chemical compound that is added in small amounts to a solution so that the pH (acidity or basicity) of the solution can be determined visually. Normally, the indicator causes the color of the solution to change depending on the pH.

Span Chemie pH indicator product range includes pH indicator powders, pH indicator soluitions-Ready to use & pH indicator papers.

Applications: 

• pH indicators are frequently employed in titrations in analytical chemistry and biology to determine the extent of a chemical reaction. 

An indicator may be used to obtain quite precise measurements of pH by measuring absorbance quantitatively at two or more wavelengths.
