What happens when hydrochloric acid is added to zinc granules?

What happens when hydrochloric acid is added to zinc granules?

When dilute hydrochloric acid is added to granulated zinc placed in a test tube, zinc metal is converted to zinc chloride and hydrogen gas is evolved in the reaction. In the reaction we can see that a zinc chloride salt is formed and hydrogen gas is evolved. The evolved hydrogen gas is colourless and odourless.

What is the balanced equation for zinc and hydrochloric acid?

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

Does zinc hydroxide react with hydrochloric acid?

Like the hydroxides of other metals, such as lead, aluminium, beryllium, tin and chromium, Zinc hydroxide (and Zinc oxide), is amphoteric. Thus it will dissolve readily in a dilute solution of a strong acid, such as HCl, and also in a solution of an alkali such as sodium hydroxide.

What is the balanced equation for sodium carbonate and hydrochloric acid?

When solutions of sodium carbonate and hydrochloric acid are mixed, the equation for the hypothetical double displacement reaction is: Na2CO3 + 2 HCl → 2 NaCl + H2CO3 Bubbles of a colorless gas are evolved when these solutions are mixed.

What are the products obtained when NaHCO3 reacts with HCl?

A saturated solution of sodium bicarbonate is reacted with hydrochloric acid to form carbon dioxide gas.

Which acid is the strongest one among acids?

perchloric acid

Will hydrofluoric acid eat through plastic?

Hydrofluoric acid won’t eat through plastic. It will, however, dissolve metal, rock, glass, ceramic. Hydrofluoric acid (HF) is a solution of hydrogen fluoride in water. Hydrofluoric acid is a highly corrosive acid, capable of dissolving many materials, especially oxides.

Why is hydrofluoric acid stored in plastic bottles?

Because of the high reactivity toward glass and moderate reactivity toward many metals, hydrofluoric acid is usually stored in plastic containers (although PTFE is slightly permeable to it).

Is plastic acidic or basic?

All plastics up to polymers with macromolecular chains of saturated hydrocarbons possess both acidic and basic properties. Thus, for example, polyethylene terephthalate (PET) according to general assumptions is a base and polyvinylchloride (PVC) and polymethylmethacrylate (PMMA) are acids.

What kind of acid will dissolve glass?

Hydrofluoric acid
