Which metal reacts the fastest with acid?
magnesium
The metal which reacts fastest is magnesium; it reacts vigorously with hydrochloric acid.
Which metal react fastest with dilute Sulphuric acid?
Explanation: Amongst the metals iron,magnesium,zinc and aluminium, which reacts 1) fastest with dil. sulphuric acid and. 2)slowest with dil.
Which metal is least reactive zinc or lead?
In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom….The reactivity series.
| Element | Reaction with dilute acids |
|---|---|
| Magnesium | Quickly |
| Zinc | More slowly |
| Iron | More slowly than zinc |
| Copper | Very slowly |
Which metal does react with Sulphuric acid?
Dilute sulfuric acid reacts with metals higher than hydrogen in the reactivity series to form sulfate salts and hydrogen gas. Note the metal reactions are different with concentrated sulfuric acid. Iron is cleaned free from rust prior to coating with tin to form tinplate and with zinc to form galvanized iron.
How does sulphuric acid reacts with I Zn II Al?
Reaction of zinc with acids Zinc metal dissolves slowly in dilute sulphuric acid to form solutions containing the aquated Zn(II) ion together with hydrogen gas, H2. In practice, the Zn(II) is present as the complex ion [Zn(OH2)6]2+.
Which gas is evolved when zinc is added to hydrochloric acid?
hydrogen gas
When zinc reacts with hydrochloric acid, the reaction bubbles vigorously as hydrogen gas is produced. The production of a gas is also an indication that a chemical reaction is occurring. Zinc reacting with hydrochloric acid produces bubbles of hydrogen gas.
Does zinc react with dilute acid?
Dilute acids react with relatively reactive metals such as magnesium, aluminium, zinc and iron. The products of the reaction are a salt plus hydrogen gas. Here’s a good way to remember it: MASH (M+A→S+H). In general, the more reactive the metal, the faster the reaction.
Which metal among the following metals is most reactive?
– So, out of given metals, Potassium is the most reactive metal. Therefore, potassium is the most reactive metal among the given options.
Does Zinc react with sulfuric acid?
Zinc reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas is evolved. Since the products zinc sulphate and hydrogen gas are entirely different in chemical composition and chemical properties from the reactants, the reaction is a chemical change.
How does sulphuric acid react with metal?
Sulfuric acid is very reactive and dissolves most metals, it is a concentrated acid that oxidizes, dehydrates, or sulfonates most organic compounds, often causes charring. It reacts with most metals, particularly when diluted with water, to form flammable hydrogen gas, which may create an explosion hazard.
What happens when zinc metal reacts with sulphuric acid?
When zinc reacts with dilute sulphuric acid hydrogen gas is evolved, with an effervescence. How will you test the gas evolved in the reaction between zinc and dilute Sulphuric acid? Zinc metal gives hydrogen gas when it is treated with dilute sulphuric acid. Therefore, the gas evolved is hydrogen.
What happens when an acid reacts with a metal?
When acids react with metals, the products are a salt and hydrogen. Zinc and iron also react with hydrochloric acid. Magnesium, zinc and iron also react with sulfuric acid. The products are a salt (in this case a sulfate) and hydrogen.
What happens when aluminium reacts with dilute hydrochloric acid?
Reaction of aluminium with dilute hydrochloric acid: Aluminium chloride and hydrogen gas are formed. Reaction of zinc with dilute sulphuric acid: Zinc sulphate and hydrogen gas are formed when zinc reacts with dilute sulphuric acid. This method is used in laboratory to produce hydrogen gas.
What are the products of a reaction with sulfuric acid?
Magnesium, zinc and iron also react with sulfuric acid. The products are a salt (in this case a sulfate) and hydrogen. For example: Name the two products of the reaction of zinc with hydrochloric acid. The products are zinc chloride and hydrogen.
