Question

question 49 (4 points) give the systematic name for ni(h2po3)3 (credit will not be given for older style names)

Explanation:

Step1: Identify the cation

The cation is nickel (\(Ni\)). Since nickel can have multiple oxidation states, we need to determine its oxidation state in the compound.

Step2: Identify the anion

The anion is \(H_2PO_3^-\), which is called dihydrogen phosphite.

Step3: Determine the oxidation state of nickel

In \(Ni(H_2PO_3)_3\), each \(H_2PO_3^-\) has a - 1 charge. Since there are 3 \(H_2PO_3^-\) ions, the total negative charge is - 3. For the compound to be neutral, the nickel ion must have a + 3 oxidation state.

Step4: Write the systematic name

The systematic name is nickel(III) dihydrogen phosphite.

Answer:

nickel(III) dihydrogen phosphite
