If `beta_(1),beta_(2)` and `beta_(3)` are stepwise formation constants of MCl, `MCl_(2), MCl_(3)` and K is the overall formation constant of `MCl_(3)`, then ( charges omitted) `:`

For the complex ML_(2) , Stepwise formation constants M+L to ML ML+L to ML_(2) are 4 and 3 respectively. Hence, overall stability constant for M+2L to ML_(2) is :

The equilibrium constants for the stepwise formation of MCI , MCl_2 and MCI_3 are a, b and c respectively. If the equilibrium contant of formation of MCI_3 is K, which of the following is correct?

The formula of chloride of a metal M is MCl_3 , then the formula of the phosphate of metal M will be:

An element forms compounds of the type MCl_(3), M_(2)O_(5) and Ca_(3)M_(2) but does not form MF_(5) . The element could be :
