Write answers to the following questions and explain your answers.
M is a bivalent metal. Write down the steps to find the chemical formulae of its compounds formed with the radicals, sulphate and phosphate
M is bivalent which means it has a valency of 2.
(i)For sulphate
Step 1: To write the symbols of the radicals. (Basic radical on the left.)
M SO4
Step 2: To write the valency below the respective radical.
M SO4
+ 2 -2
Step 3: To cross-multiply as shown by the arrows the number of the radicals.
Step4: To write down the chemical formula of the compound in the simplest form.
MSO4
(ii) for phosphate
Step 1:To write the symbols of the radicals. (Basic radical on the left.)
M PO4
Step 2: To write the valency below the respective radical.
M PO4
+ 2 -3
Step 3: To cross-multiply as shown by the arrows the number of the radicals.
Step4: To write down the chemical formula of the compound in the simplest form.
M3(PO4)2
