Question #c83dc
1 Answer
pH =
Explanation:
You're dealing with a neutralization reaction between sulfuric acid, a strong acid, and potassium hydroxide, a strong base.
This reaction will produce potassium sulfate, a salt, and water. To get an idea about how this reaction works, write the balanced chemical equation first
The
Use the volumes and molarities of the two solutions to see how many moles you add together
and
You have equal numbers of moles of each reactant, which means that potassium hydroxide will act as a limiting reagent. In other words, you have insufficient moles of potassium hydroxide to react will all the moles of sulfuric acid.
This means that the reaction will only consume
The remaining sulfuric acid will be in excess
To determine the pH of the solution, you first need to determine the concentration of protons present.
Since each mole of sulfuric acid dissociates to produce two moles of protons, you'll have
The total volume of the solution will be
The molarity of the protons will be
The pH of the solution will thus be
