WebThe element strontium forms a nitrate, Sr(NO3)2, which decomposes on heating as shown below. 2Sr(NO3)2--> 2SrO + 4NO2 + O2 Using oxidation numbers, explain why the reaction involves both oxidation and reduction. I have got that oxygen has been oxidised from-2 to 0. Now in an answer booklet it says that N has been reduced from +5 to +4--How is this? WebThe active substance in Protelos, strontium ranelate, acts on the bone structure. Once in the gut, strontium ranelate releases strontium, which is absorbed into the bone. Exactly how strontium works in osteoporosis is not fully understood, but it is known to stimulate bone formation and reduce bone breakdown.
