what is an acid? What is a base?

Answer:

An acid is a substance that donates hydrogen ions. Now there are more hydrogen ions than hydroxide ins in the solution. This kind of solution is acidc. A base is a substance that accepts hydrogen ions. When a base is dissolved in water, the balance between hydrogen ions and hydroxide ions moves the other way.

Explanation:

Answer:

An acid–base reaction is a chemical reaction that occurs between an acid and a base. It can be used to determine pH.

Explanation:

An acid is a substance that donates protons or accepts a pair of valence electrons to form a bond.

A base is a substance that can accept protons or donate a pair of valence electrons to form a bond. Bases can be thought of as the chemical opposite of acids.

In the United States, alcoholic beverages that are sold in stores display a government warning stating that pregnant women should not drink alcoholic beverages. This is because
it prevents cleavage division from occurring, so a zygote cannot become a blastocyst.
if a woman drinks alcohol while she is pregnant, she may not be able to ovulate again after childbirth.
studies have proven that alcohol consumption causes long-lasting disorders in the fetus.
the science of chemistry has shown that alcohol is a reactive substance that may interfere with the mother’s food digestion.
