Question

how will you show that ethanoic acid is acidic in nature

Answer 1

we can identify its acidic nature by its ph value.pH is the scale which measures the concentration of H+ or H3O ions in a substance. 7 is the pH of pure water, this is neutral(neither acidic nor basic)in nature. Nos 1–6 show acidic naturewhile 8-14 show basic nature. Therefore pH of an acid can range from nos 1 to 6.

Answer 2

It is simple

For checking acidic nature

Litmus paper are usually used

If blue litmus turned red then you can say acidic.

But if you dont have litmus paper then you can use phenolpthalien or turmeric.
