Which statement regarding acids and bases is correct?
A) Acids increase the pH, and bases decrease the pH.
B) Acids increase the proportion of hydrogen ions (H+) , and bases reduce the proportion of H+.
C) Acids are harmful, but bases are not harmful.
D) Acids combine with bases to form buffers.
E) Acids combine with bases to form sugars.
Hydrogen Ions
Positively charged atoms of hydrogen, which contribute to acidity when present in high concentrations in solutions.
Acids
Substances that release hydrogen ions (H+) when dissolved in water, typically having a sour taste and capable of turning blue litmus paper red.
Bases
Chemical substances that can accept hydrogen ions (H+) and are characterized by a pH greater than 7 when dissolved in water.
- Understand the basic concepts of acids, bases, and pH levels, including their effects on hydrogen ion concentration.

Final Answer :
B
Explanation :
Acids increase the proportion of hydrogen ions (H+) in a solution, while bases reduce the proportion of hydrogen ions. This is reflected in the pH scale, where a pH of 0-6.9 is acidic, 7 is neutral, and 7.1-14 is basic or alkaline. Statement A is incorrect, as bases increase the pH and acids decrease it. Statement C is incorrect, as both acids and bases can be harmful depending on their concentration and the situation. Statement D is partially correct, as acids and bases can combine to form buffers, but this is not the only product that can be formed. Statement E is incorrect, as acids and bases do not combine to form sugars.
