Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
weight of evidence
Reliability:
2 (reliable with restrictions)
Justification for type of information:
Calcium is highly reactive in water. In powdered form, the reaction with water is extremely rapid. In water reaction calcium is forming insoluble calcium hydroxide. In water solutions of acids where the salt is water soluble, calcium reacts vigorously. Calcium metal is classified hazardous (DSD) because of violent reactions with water and acids.
