Hello!
Similarities:
-They can conduct electric current because they both are ionic substances.-
-They both form Water and Salt when neutralized.
Differences:
-Acids release Hydronium ions (H₃O⁺) when hydrolyzed while Bases release Hydroxyl ions (OH⁻) when hydrolyzed.
-Acids are commonly formed with non-metals (such as Chlorine, Sulfur, Oxygen, and Nitrogen) while Bases are commonly formed with metals (such as Sodium, Potassium, Calcium, and Copper).
Have a nice day!

c. physical change
Explanation:
The separation of ink into its different pigments during chromatography is a physical change.
Ink is a mixture of many different pigments.
During chromatography, a mixture is separated based on the relative migration of constituents of mixture over an adsorbent.
- Separation techniques are used to celebrate mixtures based on their physical properties.
- During a physical change only the physical properties of matter like their form and state is changed.
- The process is easily reversible and no new kinds of matter are formed.
