The formula for calcium hydroxyapatite in bone is Ca6(PO4)10(OH)2. When the body produces acid forming metabolites from foods and drugs?
Calcium is deposited on bones
Calcium is lost from bones
Hydrogen ion is lost from bones
hydroxide ion is deposited on the bone
Homework Answers
Calcium hydroxyapatite contain Hydroxide ion and when the acid ( prodcued in our body ) react it with it form Ca- salt which deposit in our bone . So correct option is A.

(Q#1) Hydroxyapatite has the formula Ca5(PO4)3(OH) and is the main mineral component of dental enamel and bone, and encourages bone growth when placed as bone graft. Hydroxyapatite is prepared from aqueous acid and dilute calcium hydroxide solution. If you mix 115 g of 80.2 % by mass phosphoric acid solution with 74.8 g of calcium hydroxide, what mass in g of hydroxypatite is formed assuming the reaction goes to completion?
