Question

write 3 properties of each of acids and bases.
​

Answer 1

Explanation:

Acids give off H+ (Hydrogen) ions in water; bases give off OH- (Hydroxide) ions in water.

 Acids generally taste sour due to the sour H+ ion; bases taste bitter due to the OH- ion; but they may have other tastes depending on the other part of the molecule. Bases are usually soapy in nature.

Answer 2

Answer:

Chemical Properties of Acids  

• Acids change the colour of litmus from blue to red.
• They convert the colour of Methyl Orange from Orange/Yellow to Pink.
• Acids turn the pink colour of Phenolphthalein to colourless.
• Acids can conduct electricity.
• Some Acids are highly corrosive in nature which means that they corrode or rust metals.
• Acids tend to evolve hydrogen gas whilst reacting with an active metal such as Zn, Mg, etc.
• They produce H+ ions when mixed with water.

Chemical Properties of Bases

• Bases change the colour of litmus from red to blue.
• Bases lose their basicity when mixed with acids.
• Bases react with acids to form salt and water. This process is called Neutralisation Reaction(Read).
• They can conduct electricity.
• Bases feel slippery or soapy.
• Some bases are great conductors of electricity.
• Alkalis are bases that produce hydroxyl ions (OH-) when mixed with water.
