Step-by-step explanation:
Bases are the substances that have pH value more than 7.Bases are slippery in nature and they have a bitter taste.
When bases are dissolved in water then they dissociate into ions.
Whereas acids are the substances that have pH value less than 7. Acids are sour in taste and when dissolved in water then they dissociate into ions.
Therefore, we can conclude that substances are identified according to their properties as follows.
- feels slippery - only bases
- conducts electricity - both acid and base
