Which metal is not reactive with acid?
We know gold is a noble metal and it lies below hydrogen in the reactivity series and thus it is unreactive towards acids.
Which metal does not react with hydrochloric acid even on heating?
copper does not react with dilute hydrochloric acid even on heating but reacts with sulphuric acid .
Which metal is more reactive with hydrochloric acid?
Hydrochloric acid (HCl) reacts readily with most metals other than those in the platinum group in the periodic table. Generally, the metals at the far left of the periodic table react most strongly, and as you progress towards the right side, reactivity lessens.
Which metal is most reactive with hydrochloric acid?
7.3 The Relative Activity of Metals
| METAL | WATER | HCl |
|---|---|---|
| sodium | Highly reactive in water. | Highly reactive in acid. |
| magnesium | No reaction in water at room temperature. | Reacts rapidly in acid. |
| aluminum | No reaction in water at room temperature. | No reaction. |
| iron | No reaction in water. | No reaction. |
Why copper does not react with HCl but react with h2so4?
Copper does not react with dilute sulphuric acid. This is because copper is lower in reactivity series than hydrogen. Copper has higher reduction potential than that of hydrogen. Thus, copper does not react with dilute sulphuric acid, liberating hydrogen.
What metals can react with hydrochloric acid?
These metals — beryllium, magnesium, calcium and strontium — react with hydrochloric acid to form a chloride and free hydrogen. Metallic magnesium when combined with hydrochloric acid, will naturally result in magnesium chloride — used as a dietary supplement — with the hydrogen being released as a gas.
Does Zn react with HCl?
When zinc reacts with hydrochloric acid it produces zinc chloride and hydrogen gas.
Does gold react with hydrochloric acid?
Gold is unaffected by air, water, alkalis and all acids except aqua regia (a mixture of hydrochloric acid and nitric acid) which can dissolve gold. It will, for example, react very slowly with chlorine gas at room temperature to form gold chloride, AuCl3.
Does Aluminium react with hydrochloric acid?
Aluminium is a malleable, light, silvery-white metal. Aluminium reacts with dilute hydrochloric acid at room temperature. The metal dissolves in hydrochloric acid, yielding aluminium chloride and colourless hydrogen gas. This reaction is irreversible, as the final products will not react with each other.
How would you know that CU will not react with HCl?
Copper is a less reactive metal, hence does not react with any acid. D. But Cu does not react with HCl because the reduction potential of Cu is higher than that of hydrogen. Only metals which have their reduction potential less than that of hydrogen react with non – oxidising acids.
Does zinc react with hydrochloric acid?
When zinc reacts with hydrochloric acid it produces zinc chloride and hydrogen gas. We can measure the rate of the reaction by measuring how fast the reaction produces hydrogen.
