Calcium phosphate | Ca3(PO4)2 - PubChem

Calcium Phosphate is the calcium salt of phosphoric acid with widely used appliions. This agent can be used as a countermeasure for exposure to strontium and radium radionuclides. Upon oral uptake, calcium phosphate competes for and blocks the absorption of radium (Ra-226) and strontium in the gastrointestinal (GI) tract.

Living Science 2019 2020 for Class 8 Science Chapter 4

Answer: When metal M 3 is reacted with a salt of metal M 4 then it displaces metal M 4 from its salt solution and salt of metal M 3 is formed. But when metal M 4 is reacted with a salt of metal M 3, no reaction takes place. Hence, metal M 3 is more reactive than metal M 4, because it displaced metal M 4 from its salt solution but metal M 4 could not displace metal M 3 from its salt solution.
