Text Solution

AI Generated Solution

To calculate the effective atomic number (EAN) of nickel in the complex ion \([Ni(CN)_4]^{2-}\), we can follow these steps: ### Step 1: Determine the oxidation state of nickel (Ni) The overall charge of the complex ion is \(-2\). The cyanide ion (CN) has a charge of \(-1\) and there are four cyanide ions. Therefore, we can set up the equation for the oxidation state \(x\) of nickel as follows: \[ x + 4(-1) = -2 \] ...
