State three examples each of acids, bases, and salts commonly used in therapeutic processes.
For acids used in therapeutic processes, we can mention here Aspirin (the acetylsalicilic acid or ASA), Vitamin C (the ascorbic acid) and boric acid H3BO3. Aspirin is used in flu treatment, Vitamin C is essential for human nutrition, and boric acid is used as a disinfectant and anti-bacterial factor for wounds.
For bases we can enumerate magnesium hydroxide Mg(OH)2 used as antacid in stomach pain, calcium hydroxide Ca(OH)2 used as an astringent, and the aqueous solution of sodium bicarbonate (NaHCO3(aq)) which has a mildly basic character, used also as an antacid.
Examples of salts are sodium fluoride NaF used in all toothpaste products, gypsum or calcium sulphate CaSO4*2H2O (used in plaster casts), and sodium chloride (NaCl) used in physiological serum.
