Why zinc need to dissolved completely in hydrochloric acid when determine the formula unit of zinc chloride?
Zinc needs to be completely dissolved in hydrochloric acid to ensure that all the zinc ions are released into the solution, allowing for accurate stoichiometric calculations. This complete dissolution ensures that the reaction with hydrochloric acid is complete, forming zinc chloride and hydrogen gas. If zinc is not fully dissolved, it may lead to an incomplete reaction and skew the results, affecting the determination of the formula unit of zinc chloride. Accurate measurements of the resulting zinc chloride can only be achieved when all reactants are fully consumed.

Is the compound HCI an acid or base?
It is an Acid, known as Hydrogen chloride (and Hydrochloric acid, when it is dissolved in water)
If solid sodium hydroxide were added to neutralize the HCl would this reverse the reaction and cause the sodium chloride to redissolve?
No, adding solid sodium hydroxide to neutralize hydrochloric acid (HCl) would not cause sodium chloride to redissolve. The reaction between sodium hydroxide and hydrochloric acid forms water and sodium chloride, which remains in its dissolved form. The addition of solid sodium hydroxide would simply further neutralize the acid and increase the concentration of the resulting sodium chloride solution.
Name two compounds which are covalent when pure but ionise to give ions when dissolved in water?
Hydrogen chloride and hydrogen fluoride are two examples of compounds that are covalent when pure but ionize to give ions when dissolved in water. When dissolved in water, hydrogen chloride forms H+ and Cl- ions, and hydrogen fluoride forms H+ and F- ions.
How many moles of hydrochloric acid must be dissolved in 2.50 L of water to make a 0.19 M solution?
Hydrochloric acid is a mixture water: acid with different concentrations.For hydrogen chloride (HCl) you need 0,475 moles.
What is hydrochloric acid and is it in salt?
Hydrochloric acid is a strong acid often used in industrial processes and laboratory settings. It is not found in salt; salt is typically a compound of sodium and chloride ions, where chloride is derived from hydrochloric acid.
What is the difference between hydrogen chloride and hydrochloric acid?
Hydrochloric acid is hydrogen chloride dissolved in water.
Is hydrogen chloride and acid?
Yes, hydrogen chloride is acidic when dissolved in water because it forms hydrochloric acid. Hydrochloric acid is a strong acid that can dissociate almost completely in solution to release hydrogen ions.
What is aqueous hydrogen chloride?
Aqueous hydrogen chloride is a solution of hydrogen chloride gas dissolved in water. It forms hydrochloric acid when dissolved in water. It is a strong acid.
What is added to hydrogen chloride gas to make hydrochloric acid?
Water. Hydrochloric acid is just hydrogen chloride gas dissolved in pure water.
When do you call HCl as hydrogen chloride and when do you call hydrochloric acid?
HCl is called hydrogen chloride when it is in its gaseous form, and hydrochloric acid when it is dissolved in water.
Does hydrogen chlorine dissolve?
Assuming that the question is asking if hydrogen chloride is soluble in water, yes. Hydrogen chloride, when dissolved in water, becomes Hydrochloric acid.
How does hydrochloric acid dissociate when dissolved in water?
When hydrochloric acid is dissolved in water, it dissociates into hydrogen ions (H) and chloride ions (Cl-). This process is known as ionization.
Is the compound HCI an acid or base?
It is an Acid, known as Hydrogen chloride (and Hydrochloric acid, when it is dissolved in water)
What is hydrogen chloride known as?
Hydrogen chloride in aqueous solution is commonly known as hydrochloric acid.
What are the differences between hydrogen chloride and hydrochloric acid?
Hydrogen chloride is a gas composed of hydrogen and chlorine atoms, while hydrochloric acid is a solution of hydrogen chloride gas dissolved in water. Hydrogen chloride is a pure substance, while hydrochloric acid is a chemical compound. Hydrogen chloride is a gas at room temperature, while hydrochloric acid is a liquid.
What ions are formed when ammonia is dissolved in Hydrochloric acid?
When ammonia is dissolved in hydrochloric acid, it reacts to form ammonium ions (NH4+) and chloride ions (Cl-). This reaction results in the formation of ammonium chloride (NH4Cl) as a salt.
When hydrogen chloride is dissolved in water to form hydrochloric acid what happens to the hydrogen chloride?
when hydrogen chloride is dissolved in water to form hydrochloric acid, the hydrogen chloride turns to HCL subscript 38 because of the water molecules. i also believe that they change from clear to a misty green colour but it may just be the result of a dirty test tube.
