Short answer questions
(a) baking soda is a base as it follows all the properties of bases. It is bitter in taste and when it is mixed with water, has a soapy texture.
(b) phenolphthalein remains colorless is acidic solution and turns pink in basic solution. As it didn’t show any color change in X, X is acidic in nature.
(c) acids are sour in taste. Bases are bitter in taste. All acids are soluble in water. Not all bases are soluble in water. Acids have a ph below 7. Bases have a ph above 7.
Long answer questions
Neutralization is a process in which acids and bases react with each other to neutralize the solution and produce a salt. Both the acid and base should be equally corrosive in nature to neutralize the solution completely. If the acid is more corrosive than the base, then the salt formed would be acidic in nature. A neutralized solution is the one which has a ph of 7.
Example: when we suffer from acidity, we take ENO, which is a base. The base neutralizes our acidic stomach and we get relief from acidity.
