What else can I help you with?
How could you determine whether a white powder was zinc sulfide or sodium carbonate using a hydrochloric acid solution?
Silver nitrate would not react with HCl while Zinc Sulphide would react with HCl forming Zinc Chloride and evolving H2S gas. AgNO3 +HCl---> No reaction ZnS + 2HCl -------> ZnCl2 + H2S
What do you get if you mix Ag with Na2S?
There will be no reaction. It will remain a mixture.
What compounds are responsible for the result of lead acetate test?
The lead acetate test is used to detect the presence of sulfides in a sample. This test results in the formation of a black precipitate of lead sulfide (PbS) when lead acetate is added to a solution containing sulfide ions. Lead sulfide is insoluble and appears as a dark-colored solid.
What will happen when you mix hydrochloric acid and sulphuric acid and salt?
Mixing hydrochloric acid and sulfuric acid will result in the formation of hydrogen chloride gas and heat. Adding salt to this mixture will not have a significant effect on the reaction, as salts are generally inert in acidic solutions. It is important to handle these acids with caution due to their corrosive nature.
What is the result after heating copper wire and sulfur powder?
Heating copper wire and sulfur powder together will result in the formation of copper sulfide. Copper sulfide is a compound where copper and sulfur atoms are chemically bonded together.

What amino acid will yield a positive result with lead acetate test?
Cysteine will yield a positive result with the lead acetate test due to the formation of lead sulfide. Lead sulfide appears as a black precipitate when cysteine is present in the solution.
Does the reaction KCl Na2S result in a colored solution?
Yes, the reaction between KCl and Na2S can result in a colored solution. When KCl reacts with Na2S, it can form various colored compounds, such as potassium sulfide or potassium polysulfide, depending on the conditions of the reaction.
What is the best substance to neutralise sodium hydroxide solution?
Any acid can be used to neutralize a base such as sodium hydroxide. If you have a concentrated solution of sodium hydroxide, you could neutralize it most efficiently with a strong acid such as hydrochloric acid. You can also neutralize it with Coca Cola, or vinegar, or many other acidic chemicals, but it would require a larger amount than if you used hydrochloric acid.

What will happen if Na2S mixed with water?
When Na2S is mixed with water, it will dissociate into sodium ions (Na+) and sulfide ions (S2-). This reaction will result in the formation of a basic solution due to the presence of the sulfide ions, which will hydrolyze in water to produce hydroxide ions.
What is the result after heating copper wire and sulfur powder?
Heating copper wire and sulfur powder together will result in the formation of copper sulfide. Copper sulfide is a compound where copper and sulfur atoms are chemically bonded together.
How to test the presence of the reaction of zinc and hydrochloric acid?
Place a zinc strip in a clean test tube and add dilute hydrochloric acid. The strip dissolves and the result is a colorless solution. The products are zinc chloride and gaseous hydrogen.
What result of Potassium iodide Ammonium sulfide?
Nothing happens
What tests would you use to identify a solution of Ag3PO4?
To identify a solution of Ag3PO4, you can perform a qualitative test using a phosphate test, such as adding ammonium molybdate and nitric acid, which will produce a yellow precipitate if phosphate ions are present. Additionally, you could use a silver ion test; adding a chloride solution may result in the formation of a white precipitate of AgCl, indicating the presence of silver ions. Finally, spectroscopy methods like UV-Vis could help confirm the presence of Ag3PO4 by analyzing its characteristic absorption peaks.
