A solution of 114 mL of 0.160 molecules KOH is mixed with a solution of 300 mL of 0.250 molecules NiSO4. a. write a balanced equation for the reaction that occurs. identify all phases in answer
I worked this or a very similar problem last night for another post. I suspect you are the same author BECAUSE of the error in molarity. It makes no sense to write 0.250 molecules NiSO4. I'm sure you meant 0.250 molar NiSO4. Anyway, go back and look at your other post and you'll know what to do.
To write a balanced equation for the reaction between KOH (potassium hydroxide) and NiSO4 (nickel sulfate), we need to first identify the chemical formulas for each compound.
The chemical formula for potassium hydroxide is KOH, and the chemical formula for nickel sulfate is NiSO4.
Now, let's write the balanced equation by following these steps:
Step 1: Write the formulas for the reactants on the left side of the equation and the products on the right side of the equation.
KOH + NiSO4 → ??
Step 2: Identify the products formed by combining the elements from the reactants.
From the reactants, we can see that potassium (K) combines with sulfate (SO4), and nickel (Ni) combines with hydroxide (OH).
The product formed by combining K with SO4 is K2SO4 (potassium sulfate) because K has a +1 charge, and SO4 has a -2 charge. Hence, we need two potassium ions to balance the charge of the sulfate ion.
The product formed by combining Ni with OH is Ni(OH)2 (nickel hydroxide) because Ni has a +2 charge, and OH has a -1 charge. Therefore, we need two hydroxide ions to balance the charge of the nickel ion.
KOH + NiSO4 → K2SO4 + Ni(OH)2
Step 3: Balance the number of atoms in the equation by adding coefficients or numbers in front of the formulas.
Now, let's balance the equation.
2 KOH + NiSO4 → K2SO4 + Ni(OH)2
The balanced equation for the reaction between KOH and NiSO4 is:
2 KOH + NiSO4 → K2SO4 + Ni(OH)2
Let's now identify the phases (states) for each compound:
2 KOH (aq) + NiSO4 (aq) → K2SO4 (aq) + Ni(OH)2 (s)
In the balanced equation, (aq) represents aqueous solution or liquid phase, and (s) represents solid phase.
