Question

when you had a few drops of Acetic Acid to a test tube containing sodium bicarbonate powder which of the following is your observation​

Answer 1

Ch3CooNa + h2o+co2

Will be formed

Its in ncert on of 74

Answer 2

$\huge\mathcal{ANSWER}$

⚫ACETIC ACID

Its a carboxylic acid which contains of two carbon atom and shows all properties of acid, but is weak in nature.

⚫SODIUM BICARBONATE

Its a compound formed when sodium loses its one electron to bicarbonate radical.

${Na}^{+1}\longrightarrow {HCO_3}^{-1}$

$[{Na}^{+1}][{HCO_3}^{-1}]$

◼$\bold{EXPERIMENT}$

▶Take a test tube with a few drops of acetic acid and add sodium bicarbonate powder ti it.

◼$\bold{OBSERVATION}$

▶A colourless odourless gas evolves with water.

▶Formation of sodium acetate takes place

◼$\bold{TEST \: FOR \: CO_2}$

▶When burning extinguisher is brought near to test tube it extinguishes.

▶It turns blue litmus faint red.

▶When carbon dioxide is passed over lime water, lime water turns milky and on excess passage the milkiness disappears.

▶It has no effect on $KMnO_4 \: or \: K_2Cr_2O_7 \: solution$

◼$\bold{EQUATIONS}$

For experiment :--

▶$2CH_3COOH + Na_2CO_3 \longrightarrow 2CH_3COONa + H_2O \uparrow$

For test of carbon dioxide :--

◼$Ca(OH)_2 + CO_2 \longrightarrow CaCO_3(white ppt)$

◼$CaCO_3+ CO_2 + H_2O\longrightarrow Ca(HCO_3)_2(white ppt)$
