• Bases are bitter in taste.
• Their pH value is greater than 7.
• Good conductor of heat and electricity in aqueous solution.
• Bases have a slippery appearance.
• Example: Sodium hydroxide, Baking soda etc.

Final answer: Acids and bases can be differentiated by pH having less than 7 pH value are acid and greater than 7 are bases.
