question 5 (1 point) when cobalt (ii) cation combines with chloride anion, how many chloride anions will be in the formula? a) 3 b) 7 c) 2 d) 1
Answer
Explanation:
Step1: Determine ion charges
Cobalt (II) cation has a charge of +2 ($Co^{2 +}$), and chloride anion has a charge of - 1 ($Cl^{-}$).
Step2: Balance charges
To balance the +2 charge of cobalt (II) cation, we need 2 chloride anions since $2\times(-1)+2 = 0$.
