This question is about acids, alkalis, and titrations.
Which ion do all acids produce in aqueous solution?
- OH−\text{OH}^-OH−
- H+\text{H}^+H+
- O2−\text{O}^{2-}O2−
- Cl−\text{Cl}^-Cl−
Potassium hydroxide solution reacts with an acid to form potassium nitrate. Complete the word equation for the reaction. potassium hydroxide+____________ acid→potassium nitrate+____________\text{potassium hydroxide} + \text{\_\_\_\_\_\_\_\_\_\_\_\_ acid} \rightarrow \text{potassium nitrate} + \text{\_\_\_\_\_\_\_\_\_\_\_\_}potassium hydroxide+____________ acid→potassium nitrate+____________
A student carries out a titration to find the concentration of a potassium hydroxide solution. They use a piece of apparatus to add dilute nitric acid to a conical flask containing the potassium hydroxide.
Name apparatus B.
Determine the volume reading shown on the zoomed-in scale on apparatus B.
The student has two different bottles of potassium hydroxide solution, labeled X and Y.
The higher the concentration of the potassium hydroxide solution, the greater the volume of dilute nitric acid needed to neutralise it.
Describe how the student could use titrations to find which solution, X or Y, is more concentrated.
