What colour does litmus indicator turn when put in sodium hydrogen-carbonate?
When litmus indicator is put in sodium hydrogen-carbonate (a mild base), it turns blue. Sodium hydrogen-carbonate, also known as sodium bicarbonate, has a basic pH, which causes the blue color change in the litmus paper. In acidic solutions, litmus would turn red, but in this case, the basic nature of sodium hydrogen-carbonate results in a blue coloration.

Why alkaline solution containing ferrous ions is boiled during detection of nitrogen?
To convert ferrous ions to ferric as Fe2(SO4)3 .which then react with sodium ferrocyanide to give prussian blue colour.
Does hydrazine answer the test for nitrogen in Lassaignes test?
Yes, hydrazine will give a positive test for nitrogen in Lassaigne's test. When hydrazine is present in the organic compound being tested, sodium fusion test in Lassaigne's test will produce sodium cyanide which upon acidification and addition of iron(III) chloride, will give a Prussian blue color, confirming the presence of nitrogen.
What happens to the indicator when hydrochloric acid is added to sodium hydroxide?
It turns from its original blue colour to red.
