Answer

$2KOH(aq) + NiSO_4(aq) --> Ni(OH)_2(s) + K_2SO_4(aq)$

Work Step by Step

1. Write the unbalanced equation: $KOH + NiSO_4 --> Ni(OH)_2 + K_2SO_4$ 2. Balance the equation: Start fixing the number of K atoms, by multiplying KOH by 2: $2KOH + NiSO_4 --> Ni(OH)_2 + K_2SO_4$ Now the equation is totally balanced.
