Arrange the following point in sequence for derivation of formulae of compounds.(a) The valencies of the ions or radicals are written below the radicals without positive and negative sing.(b)If the valencies have common factors , they are divided by the highest common factor.(c ) The magnitude of valencies should be interchanged and writtenassubscripts on the right side of the respective ions.(d) The positive radical followed by negative radical are written with their chatges.(e)If the radicals contain more than one atom , they are enclosed in brackets and the appropriate valency (more than one ) written assubscripts outside the bracket.
Answer» bcdea dacbe abcde dabce Solution :(i) The positive radical followied by negative radicalare written with their charges. (ii)The valencies of the ions or radicals are written below the radicals without positive and negative sign. (iii) The magnitude of valencies should be interchanged and written as subscripts on the right SIDE of the respective ions. (iv)If the valencies have common factors , they are dividedby the HIGHEST common factor. (v)If the radicals CONTAIN more than one atom , they are enclosed in brackets and the appropriate VALENCY (more than one) written as subscript outside the BRACKET.
