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.
What is the gas produced when any metal reacts with acids?
Hydrogen gas is produced when any metal reacts with acids. This is a common reaction that is often used to test for the presence of metal in a substance.
What happens when sodium reacts with an acid?
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 do you do a flame test on low sodium salt?
To do a flame test on low sodium salt, first moisten a wooden splint with water and dip it into the low sodium salt. Then, heat the splint in a Bunsen burner flame and observe the color of the flame. The color produced can help identify any other metal ions present in the salt.
What happens when Acetone reacts with mercuric chloride and sodium hydroxide?
When acetone reacts with mercuric chloride and sodium hydroxide, the mercuric chloride will likely form a complex with acetone, while sodium hydroxide will react to form the sodium salt of acetone. This reaction can be used in the iodofom test to detect the presence of methyl ketones.
How can you tell whether a compound reacts with bromine?
You can test if a compound reacts with bromine by adding bromine water to the compound. If the compound reacts with bromine, the characteristic reddish-brown color of the bromine water will fade as it reacts with the compound. This reaction is often used to test for the presence of unsaturated bonds in organic compounds.
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 must a test tube be dry before adding sodium metal?
Sodium reacts violently with water, producing hydrogen gas and sodium hydroxide. If a test tube is wet, the sodium metal could react with the water present, leading to a rapid release of hydrogen gas and potential splattering or even an explosion. Ensuring the test tube is dry helps to prevent this hazardous reaction from occurring.
Why sodium extract is usually alkaline in nature?
Sodium hydroxide, commonly used in sodium extraction processes, is a strong base that contributes to the alkaline nature of the extract. When sodium hydroxide dissociates in water, it releases hydroxide ions which increase the pH of the solution, making it alkaline.
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 gas produced when any metal reacts with acids?
Hydrogen gas is produced when any metal reacts with acids. This is a common reaction that is often used to test for the presence of metal in a substance.
Which gaseous product is often produced when a metal reacts with an acid?
Hydrogen gas is often produced when a metal reacts with an acid. This reaction is a common way to test for the presence of a metal in a compound.

Copper reacts with sodium hydroxide?
Copper metal itself does not react with sodium hydroxide. But when NaOH is added to a solution of copper ions, it would form a light blue precipitate, which is copper(II) hydroxide, and will NOT dissolve with the excess alkali.
What happens when dil h2so4 is added to a small amount of sodium carbonate taken in a test tube?
When dilute sulfuric acid (H2SO4) is added to sodium carbonate (Na2CO3) in a test tube, a chemical reaction occurs where carbon dioxide gas (CO2) is produced. This gas can be observed as bubbles forming in the test tube. Additionally, sodium sulfate (Na2SO4) and water (H2O) are also formed as products of the reaction.
