Complete the word equation for the neutralization reaction:

$$nitric\; acid+potassium\; hydroxide\to \dots \dots \dots \dots \dots \dots +\dots \dots \dots \dots \dots \dots$$

Look at the student's method for their experiment:

• Measure $25.0{cm}^3$ of potassium hydroxide solution into a beaker using a measuring cylinder.
• Add a few drops of phenolphthalein indicator.
• Fill the burette to the $0.0{cm}^3$ line with dilute nitric acid.
• Add the acid quickly in large portions to the potassium hydroxide solution until the indicator changes color.
• Repeat the experiment until consistent results are obtained.

Describe and explain one improvement the student should make to their method to get a more accurate titration result.

The student repeats the titration four times. The results are shown in the table below:
