Question

Identify the substance that each property describes.

Answer 1

Explanation:

Acids are the substances that have pH less than 7. Acids are sour in taste and when dissolved in a polar solvent like water they dissociate into ions. Hence, they are able to conduct electricity.

Whereas bases are the substances that have pH more than 7. Bases are slippery in nature and when dissolved in a polar solvent like water they dissociate into ions. Hence, they are also able to conduct electricity.

Hence, we can conclude that the given substances with each property are described as follows.

• Only acid - tastes sour

• Only base - feels slippery

• both acid and base - conducts electricity

Answer 2

Answer:

conduct electricity -- NaCl

feels slippery -- diamond

taste sour -- vinegar  because the taste sour the litmus paper turn red it is acidic  acid

only acid -- hydrogen ions

only base --- caustic soda

both --- aluminum hydroxide
