learning target

By exploring whether acids and bases can react, we can initially learn to use indicators to determine whether substances undergo chemical reactions.

Understand the essence of the neutralization reaction and learn to use the neutralization reaction to change the acidity and alkalinity of the solution.

Understand the application of neutralization reactions in production and life, and understand the importance of chemistry in production and improving people's quality of life.

Neutralization reaction

Research 1: Can sodium hydroxide and hydrochloric acid react?

Experiment 1: Drop a small amount of sodium hydroxide solution into the test tube, then add a small amount of dilute hydrochloric acid, and observe the phenomenon.

How to design an experiment to prove through obvious phenomena whether sodium hydroxide and hydrochloric acid can react?

Add acid-base indicator to the mixed liquid obtained in Experiment 1,

As a result, some solutions were acidic, some were neutral, and some were alkaline.

What might be the reasons for this result?

Do these three results indicate that the two must react?

In order to be able to tell whether the alkali has disappeared when the first drop of dilute hydrochloric acid is added, when is the best time to add the indicator?
