A student is studying the properties of acetic acid. List two physical properties of acetic acid he observes. What happens when he adds a pinch of sodium hydrogen carbonate to this acid ? Write any two observations.
Acetic acid is colourless liquid.
It is miscible/ soluble in water.
On adding a pinch of sodium hydrogen carbonate,
Brisk effervescence is observed.
Evolution of a colourless/ odourless gas.
If the circuit is kept closed for a long time t resistor will get heated up and its value will change. This is because heat produced in any resistor,
H =...
Saponification reaction is a highly exothermic reaction. The reaction mixture of this reaction is basic in nature and hence, this will turn red litmus blue.
(b) Formic acid is stronger than acetic acid due to its chemical composition. Formic acid is an organic acid as well as active acid in an organic acid.
