What else can I help you with?
What cannot be used with sulphuric acid to prepare zinc sulphate?
Zinc oxide cannot be used with sulphuric acid to prepare zinc sulphate. This is because zinc oxide is insoluble in sulphuric acid, and therefore, it would not react to form zinc sulphate.
Does zinc displace hydrogen from cold water?
Zinc does not displace hydrogen from cold water, as zinc is lower in the reactivity series than hydrogen. However, if zinc is reacted with an acid, such as hydrochloric acid, it will displace hydrogen gas.
What do we get if you mix sulphric acid and zinc?
They react and form hydrogen gas and white solid compound zinc chloride. Zn + 2HCl = ZnCl2 + H2
Which out of carbon dioxide zinc chloride water and hydrogen is not produced from zinc carbonate and dilute hydrochloric?
This is hydrogen.
What is the name of zinc and sulphuric acid?
Zinc and sulfuric acid will react to form zinc sulphate and hydrogen gas.
Why copper is not used to prepare hydrogen in the laboratory?
Copper is not typically used to prepare hydrogen in the laboratory because it is not reactive enough to displace hydrogen from water or acids. Other metals like zinc or aluminum are more commonly used for this purpose as they have a higher reactivity with water or acids.
What cannot be used with sulphuric acid to prepare zinc sulphate?
Zinc oxide cannot be used with sulphuric acid to prepare zinc sulphate. This is because zinc oxide is insoluble in sulphuric acid, and therefore, it would not react to form zinc sulphate.
Can zinc be used to make tractor parts?
Pure zinc, very probable: no.
How do you prepare zinc sulfate salt strating from acid and metal?
To prepare zinc sulfate salt from acid and metal, first dissolve zinc metal in sulfuric acid to produce zinc sulfate and hydrogen gas. The hydrogen gas will bubble out of the solution, leaving behind zinc sulfate salt dissolved in water. Evaporate the water to obtain solid zinc sulfate salt.
Is zinc a pure substance?
it's a pure substance, because it's an element.
What is zinc hydrogen phosphate used for?
Zinc hydrogen phosphate, ZnHPO4, was proposed as optical material or as an ingredient in some drugs. Many applications has the zinc phosphate, Zn3(PO4)2.
Zinc and hydrogen chloride react to produce?
When zinc reacts with hydrochloric acid it produces zinc chloride and hydrogen gas.
Why calcium is not used in the lab preparation of hydrogen?
Calcium is not used in the lab preparation of hydrogen because it reacts with water to form calcium hydroxide and hydrogen gas, making it an inefficient method for producing pure hydrogen. Other methods such as using metals like zinc or aluminum are preferred for lab preparation of hydrogen as they do not form unwanted byproducts.
Why is copper not used to prepare hydrogen by the action of dilute HCL on metal?
Copper is not suitable for preparing hydrogen by the action of dilute HCl because it is less reactive than hydrogen. In a displacement reaction, hydrogen will not be displaced from hydrochloric acid by copper due to its lower reactivity. Other metals that are more reactive than hydrogen, such as zinc or magnesium, are typically used instead.
What does an acid plus zinc produce?
Hydrogen gas and a zinc salt.It produces hydrogen and zinc chloride.
What is formed when mixing HCl with zinc?
When hydrochloric acid (HCl) is mixed with zinc, zinc chloride and hydrogen gas are formed. The reaction between HCl and zinc is a single replacement reaction where the zinc replaces the hydrogen in the acid to form zinc chloride and hydrogen gas.
Why do you not use HCl with zinc to prepare oxygen?
Zinc and hydrochloric acid react to form hydrogen gas. In this reaction, zinc metal reacts with aqueous hydrochloric acid to form aqueous zinc chloride plus hydrogen gas: Zn(s) + 2HCl(aq) --> ZnCl2(aq) + H2(g) If you look carefully at the equation, oxygen is not found in any of the reactants or the products, so it would be impossible to get oxygen from this reaction.
