Describe its nature if it produces green colour in universal indicator
3 M
ii) From which acid and base, salt 'X' is formed if it produces yellow colour in univer
indicator
iii) What could be the nature of 'X' if it is formed from NaOH and CH COOH.​

Answer 1

Answer:

(i) Neutral

(ii) Weak acid

(iii)Basic

Since ,

Strong base + weak acid = basic salt

Answer 2

Explanation:

A) if the indicator shows green color.. The salt is neutral as pH will be 7
