What happens when magnesium reacts with dilute Sulphuric acid?
What happens when magnesium reacts with dilute Sulphuric acid?
Magnesium reacts with dilute sulphuric acid to form magnesium sulphate and hydrogen gas. This is a single displacement reaction and also exothermic.
What would you see when magnesium reacts with sulfuric acid?
Magnesium sulphate and hydrogen are formed when magnesium reacts with dilute sulphuric acid.
What does not react with dilute sulfuric acid?
NaNO3 does not react with a dilute solution of sulfuric acid. It is a salt of strong acid HNO3 with strong base NaOH.
Which metal reacts fastest with dilute Sulphuric acid?
Answer. Explanation: Amongst the metals iron,magnesium,zinc and aluminium, which reacts 1) fastest with dil. sulphuric acid and.
Which of the following does not use Sulphuric acid?
Among the given metals the metal which does not react with Sulphuric acid ( ) is Platinum .
Which does not dissolve in Dil h2so4?
The surface of metallic lead is protected by a thin layer of lead oxide PbO. This renders the lead essentially insoluble in sulfuric acid.
Which of the following anions does not react with Dil h2so4?
The correct option is (4) All. 2. This is because, they all are hard bases and thus do not respond when acid concentration is low in dilute solutions.
How do you test for Sulphuric acid?
Test for sulfuric acid (and soluble sulfates) Firstly, add dilute HNO3. This is to prevent precipitation of other insoluble barium compounds such as BaCO3 or BaSO3. Secondly, add Ba(NO3)2 (aq). If sulfuric acid or a sulfate is present a white precipitate will be immediately observed.
When concentrated H _( 2 so _( 4 is added to nacl solid then HCL gas is liberated because?
Answer Expert Verified When concentrated sulphuric acid is mixed with sodium chloride, it results in the formation of sodium bisulphate and the HCL gas. The moist blue litmus turns red because HCL gas is acidic in nature.
Which negative radical gives brown fumes with cold dilute H2SO4?
(d) Nitrite: On treating solid nitrite with dil. H2SO4, nitric oxide (NO) gas is evolved which readly gives brown fumes of NO2 with the oxygen of the air.
Which radical does not give test with dilute Sulphuric acid?
If some gas is evolved with dilute sulphuric acid, then there is no need for performing cone, sulphuric acid test. 2. Do not boil the salt with cone, sulphuric acid….Concentrated Sulphuric Acid Test.
| Observations | Inference | |

| 4. Reddish brown gas with pungent smell, turns FeSO4 solution black. | NO2 | NO2– |
What happens when carbon reacts with concentrated Sulphuric acid?
Carbon reacts with sulfuric acid to produce carbon dioxide and sulfur dioxide gas along with water. Sulfuric acid should be a concentrated, heated solution.
What do you observe when dilute Sulphuric acid is added to sodium sulphide?
sulphuric acid and sodium sulphite occurs in two steps and is a double replacement reaction. In the first step, sulphuric acid reacts with sodium sulphite to give sodium sulphate and sulphurous acid. In the second step, sulphurous acid, which is highly unstable decomposes spontaneously into sulphur dioxide and water.
What happens when sodium sulphide reacts with dilute Sulphuric acid?
Sodium sulphite reacts with sulphuric acid to produce sodium bisulfate, sulfur dioxide and water.
What happens when dilute Sulphuric acid is added to Sulphur?
When dilute sulphuric acid is added to the mixture of iron filings and sulphur, the iron part reacts with sulphuric acid and hydrogen gas is produced which is a colourless and odourless gas.
What happens when sodium reacts with dilute Sulphuric acid?
Reaction of sodium with acids Sodium metal dissolves readily in dilute sulphuric acid to form solutions containing the aquated Na(I) ion together with hydrogen gas, H2.
Does sulfuric acid dissolve glass?
One of the values of glass is its relative chemical inertness. Materials such as concentrated hydrochloric or sulfuric acids can be stored in glass indefinitely. However, hydrofluoric acid will react strongly with a glass container.
