Chemizorb H+ is a granulate mixture that consists of a mineral co-polymer absorbent, an alkaline neutraliser, and a pH indicator.

• Cover the spill with the amount necessary to neutralise and absorb
• pH indicator makes it possible to monitor the neutralisation process
• 100 g of Chemizorb H+ required to absorb and neutralise 100 ml of acid

The neutralisation process results in the release of CO₂. When the acid has been neutralised, the colour of the indicator changes from red to orange/yellow.
