The absorbents for alkalis, acids and hydrofluoric acid

• Easy to use
• pH indicator makes it possible to monitor the neutralisation process
• About 100 to 120 g of Chemizorb® OH^- is required to absorb and neutralize 100 ml of alkalis

Upon contact with the alkalis the absorbent first turns blue in colour and after the completion of neutralization, the blue colour becomes pale. The admixed pH indicators make it possible to keep track of the process of neutralization of the spilled acid or alkalis. It should be borne in mind that the neutralization reaction may involve the generation of heat and gas. Merck products are not available from VWR in all countries. Please check with your local distributor.

It is a powder mixture that consists of a mineral copolymer as the absorbent, an acidic salt as the neutralizer and a pH indicator.
