Acids and alkalis mixed together in equal proportions do what?

1. Produce water

2. Neutralize each other

3. Form a salt

4. Increase pH

The correct answer is: Neutralize each other

Acids are known to be corrosive and can cause damage when in contact with living tissue. Alkalis on the other hand are slippery and can cause burns when in contact with living tissue. When they are mixed together in equal proportions, they will neutralize each other and form a salt. This reaction makes the resulting solution less acidic or less basic, depending on the strength of the original acids and alkalis used. Therefore, options A, C, and D are incorrect as they do not accurately describe what happens when acids and alkalis are mixed in equal proportions.
