Cu + hcl balanced equation

What is the balanced equation for copper and hydrochloric acid?

Cu + HCl = CuCl2 + H2 – Chemical Equation Balancer.

What happens when Cu reacts with HCl?

There will be no reaction. Copper is a very unreactive metal, and it does not react with hydrochloric acid. It is above copper in a metal reactivity series, so copper cannot replace the hydrogen in HCl to form CuCl2 .

What is the change in Colour when Cu reacts with dil HCl?

It reacts with dilute HCl to form copper chloride (CuCl₂) along with water (H₂O). The copper chloride formed is bluish-green in colour, and being soluble in water, forms a bluish-green solution in it. Therefore, the colour is observed to change from black to bluish-green.

What type of reaction is CuO HCl?

Type of Chemical Reaction: For this reaction we have a double replacement reaction. Balancing Strategies: In this reaction we have CuO and HCl combining to form CuCl2 adn H2O. Thi is a double replacement chemical reaction.

Does Zn react with HCl?

The reaction between zinc and HCl is given by the symbolic equation Zn + HCl → ZnCl2 + H2. Note that H2 is hydrogen gas.

Does AG dissolve in HCl?

The reaction of silver withhydrochloric acid has no result, as this metal does not dissolve inhydrochloric acid because it is covered with a thin layer of silverchloride. This is because, like other reactive metals, silver cannot displace hydrogen from HCl.

Why does Cu react with hno3 but not HCl?

Copper does not dissolve in HCl because hydrogen can donate its electron more readily than copper that’s why hydrogen gets oxidized prior to copper and so, it does not get dissolved in HCl. Therefore in nitric acid copper is oxidised by nitrate ion and not by hydrogen ions.

Does CU react with h2so4?

Copper (II) oxide reacts with sulfuric acid to create water and copper (II) sulfate. This reaction could be classified as a double displacement reaction or a neutralization reaction.

What is the Colour of copper oxide?

Copper(I) oxide or cuprous oxide is the inorganic compound with the formula Cu2O. It is one of the principal oxides of copper, the other being CuO or cupric oxide. This red-coloured solid is a component of some antifouling paints. The compound can appear either yellow or red, depending on the size of the particles.

How can you prove that zinc is more reactive than copper?

Expert Answer:(a) We can show it by an experiment:Displacement reaction between copper and zinc:-When a strip of zinc metal is placed in CuSO4 solution, the colour of blue copper sulphate solution fades gradually.This proves that zinc displaces copper from copper sulphate solution being more reactive than copper.

Is cuso4 an acidic salt?

Copper sulphate is a salt of a strong acid, H2SO4, and a weak base, Cu(OH)2. The release of H+ ions by hydrolysis makes the solution distinctly acidic.

Does NaCl dissolve in HCl?

NaCl just get dissolve in HCl(aq) acid. This is because NaCl is formed after NaOH reacts with HCl and only after neutralization reaction of acid and alkali and after removing much of the water content, only then we can obtain NaCl.

How to write a regression equation

What is a regression equation example? A regression equation is used in stats to find out what relationship, if any, exists between sets of data. For example, if you measure a child’s height every year you might find that they grow about 3 inches a year. That trend (growing three inches a year) can be […]

Solving an absolute value equation

How do you find the absolute value? Absolute Value means and “−6” is also 6 away from zero. More Examples: The absolute value of −9 is 9. The absolute value of 3 is 3. Can you solve problems using absolute value? Solving absolute value equations is as easy as working with regular linear equations. The […]
