Canvas Classes · Accepted Answer

Step 1: Identify product A

So A =  (nickel(II) chloride)

Step 2: Identify product B

The question references a second reaction (shown in the original image) where A reacts further. Based on context, product B is  — the hexaaquanickel(II) complex.

Step 3: Count protons NOT involved in H-bonding

In :
- Total H atoms = 6 water molecules × 2 H = 12 H atoms
- The coordinated water molecules donate H-bonds to outer sphere, but the H atoms pointing inward (toward Ni) do not participate in H-bondi
