Why sodium extract is alkaline in nature?
It is because sodium reacts with water (present in test tube or porcelain basin) to give a alkaline solution of NaOH.
Why don't we react sodium with acid in the lab?
sodium + hydrochloric acid → sodium chloride + hydrogen. 2Na(s) + 2HCl(aq) → 2NaCl(aq) + H2(g) Hydrogen gas produced catches fire. The reaction is very exothermic. Metallic sodium reacts violently with water. Use a safety screen if you decide to see what happens with acid. Use small pieces of sodium and a wide mouthed reacting vessel ie a beaker rather than a test tube.

How does disappearing ink work?
When the ink is sprayed onto a porous material the water in the ink reacts with carbon dioxide in the air to form carbonic acid. The carbonic acid then reacts with the sodium hydroxide in a neutralization reaction to form sodium carbonate. Neutralizaton of the base causes a color change of the indicator and the stain disappears: Carbon dioxide in the air reacts with water to form carbonic acid: CO2 + H2O -> H2CO3 The neutralization reaction is sodium hydroxide + carbonic acid -> sodium carbonate + water: 2 Na(OH) + H2CO3 -> Na2CO3 + 2 H2O
Chemical test can distinguish sodium carbonate form potassium hydroxide?
- use a flame test to distinguish between sodium and potassium - use flame photometry to determine sodium and potassium - heat sodium carbonate and collect the gas in a beaker with water: the gas released is carbon dioxide; see the bubbles. Measure the pH; it will be more than 7.

Why sodium extract is usually alkaline in nature?
It is because sodium reacts with water (present in test tube or porcelain basin) to give a alkaline solution of NaOH.
What is the principle of Sodium hypobromite test for urea?
sodium hypobromite reacts with urea and nitrogen gas is released as brisk effervesence
Why don't we react sodium with acid in the lab?
sodium + hydrochloric acid → sodium chloride + hydrogen. 2Na(s) + 2HCl(aq) → 2NaCl(aq) + H2(g) Hydrogen gas produced catches fire. The reaction is very exothermic. Metallic sodium reacts violently with water. Use a safety screen if you decide to see what happens with acid. Use small pieces of sodium and a wide mouthed reacting vessel ie a beaker rather than a test tube.

What happens when sodium reacts with ethanol?
Sodium reacts with Ethanol to produce Sodium Ethoxide (C2H5ONa) and Hydrogen gas (H2), according to the following equation.2 C2H5OH + 2Na ----> 2 C2H5ONa + H2
What is the structure of C8H8O compound which gives a positive test of iodoform test and reacts with sodium almagam to yield C8H10O which gave negative iodoform test?
Structure of phenyl acetic acid (C8H8O2) is attached below.
Name the element produced when magnesium and metal reacts with hydrochloric acid and how could you test for the presence of this element?
Mg HO + Cl
What are three examples of qualitative?
- test of chlorine in water - test of sodium in a mixture by flame test - test of hydrogen sulphide in a gas mixture
What is a water tolerance test as regards melamine?
A water tolerance test as regards melamine is how melamine reacts to water. And melamine is quite inert as regards water, either hot or cold. It is quite impervious to damage or degradation by water.
Which metal reacts with water and burns with a lilac flame?
Potassium has a violet color in the flame test.
How do you make sodium bicarbonate Test Solution not in USP?
By dissolving in water the necessary quantity to obtain the desired concentration of sodium bicarbonate.
