Explanation:
Detailed explanation-1: -Answer: (a) Hydrogen is common to all acids. Eg: HCl, H2SO4, HNO3. This is because, when acid is dissolved in water, it gives out hydrogen ions which are protons.
Detailed explanation-2: -All acids release hydrogen (H+) ions on dissolving in water.
Detailed explanation-3: -It describes an acid as a molecule that will give away a proton-a type of subatomic particle, sometimes called a hydrogen ion-from one of its hydrogen atoms. At a minimum, that tells us that all Brønsted-Lowry acids must contain hydrogen as one of their building blocks.
Detailed explanation-4: -Acids and bases both produce ions in water solution. Acids release hydrogen ions (H+) whereas Bases release hydroxide ions (OH-).
