The solution will be basic.
Start with the balanced chemical equation for this neutralization reaction
Notice that you have a
If you have more moles of acid than of base, the solution will have an excess of hydronium ions,
If you have more moles of base, the solution will hve an excess of hydroxide ions,
You have more moles of calcium hydroxide present, which means that the sulfuric acid will be completely consumed by the reaction and you'll only be left with
Therefore, the solution will be basic.
If you need to calculate the pH as well, use the dissociation of calcium hydroxide to get the number of moles of hydroxide ions present
You'll get twice as many moles of hydroxide ions than you have of the remaining calcium hydroxide. Use the total volume of the solution to determine the molarity of the
From there, determine pOH and pH.
I don't want the initial answer to become very long, so I'll just show you how to get the solution's pH here.
So, you know that your reaction left you with excess calcium hydroxide, which is a strong base. In your case, calcium hydroixde will dissociate completely to produce calcium cations,
Notice that you get
To get the molarity of the hydroxide ions, use the total volume of the solution
This will get you
SIDE NOTE Don't forget to convert mL to L when calculating molarity!
Since you know the concentration of the hydroxide ions, you can determine the solution's pOH by
THis means that the solution's pH will be
