Question: what is the difference between acidic medium and alkaline medium?
Answer: Alkaline materials will cause an increase in the concentration of OH- in an aqueous medium. ... Acids have pH lower than 7 (H+ concentration higher than 10^-7), and bases have pH higher than 7 (H+ concentration lower than 10^-7). Acids are more sour and bases are more bitter. Acids and bases combine to form salts.
