whta are acids and bases
Answers
An acid is a substance that donates protons (in the Brønsted-Lowry definition) or accepts a pair of valence electrons to form a bond (in the Lewis definition). A base is a substance that can accept protons or donate a pair of valence electrons to form a bond.
Answer:
An acid–base reaction is a chemical reaction that occurs between an acid and a base. It can be used to determine pH.
Formula
Acid–base equilibrium
HCl(aq) + Na(OH)(aq) → H2O + NaCl. In this reaction both the sodium and chloride ions are spectators as the neutralization reaction, H+ + OH− → H2O.
Importance
Acids and bases are important in living things because most enzymes can do their job only at a certain level of acidity. Cells secrete acids and bases to maintain the proper pH for enzymes to work. For example, every time you digest food, acids and bases are at work in your digestive system.
