Ethene dissolves in con H2SO4 ethane does not explain?
Ethene is an unsaturated compound so adds up one molecule of sulphuric acid and addition product becomes dissolved in acid but ethane is a saturated compound so does not react and dissolves in sulphuric acid.
What happens in the reactions of aqueous bromide ions with aqueous silver nitrate following by the addition of concentrated aqueous ammonia?
When aqueous bromide ions react with aqueous silver nitrate, a white precipitate of silver bromide is formed. Upon addition of concentrated aqueous ammonia, the precipitate dissolves due to the formation of a complex ion called the diamminesilver(I) ion, [Ag(NH3)2]+. This reaction forms a colorless solution.
Why the solubility of salicylic acid in water change when hydrochloric acid is added?
The addition of hydrochloric acid protonates the salicylic acid molecules, converting them into their water-soluble salt form. This increases the solubility of salicylic acid in water as the salt form has greater aqueous solubility due to its ionic nature.
Conclusion for silver nitrate precipitate?
In conclusion, the formation of a white precipitate upon the addition of silver nitrate indicates the presence of a chloride ion in the solution. This reaction is commonly used in qualitative analysis to test for the presence of chloride ions in a sample.
How could you distinguish solid barium chloride?
Solid barium chloride can be distinguished by its white crystalline appearance and its solubility in water. When barium chloride is dissolved in water, a white precipitate of barium sulfate forms upon the addition of a sulfate-containing solution, due to the formation of a precipitate (BaSO₄) that is insoluble in water.

How do you identify zinc cholride?
Add sulphuric acid to salt pungent smell of HCl and white fumes with Ammonia confirm the presence of chloride, in aqueous solution of salt add H2S the black precipitate are formed, in clear solution the addition of small quantity of NaOH gives white ppts. which become soluble in excess, it is the confirmation of Zinc.
What has the author Clifford D Carpenter written?
Clifford D. Carpenter has written: 'The addition compounds of organic substances with sulfuric acid ..' -- subject(s): Sulphuric acid
What is test for purines?
The two DNA bases Adenin and Guanine belong to the group called Purines.
Name the addition product formed by ethene and water?
The addition product formed by ethene and water is ethanol. This reaction involves the addition of a water molecule across the carbon-carbon double bond in ethene, resulting in the formation of ethanol.
What happens when alcohol and perfume mixed?
it_evaporates">it evaporatesThe addition of alcohol "fixes" the scent resulting in the fragrance lasting longer on the skin.
Conclusion for silver nitrate precipitate?

Why is Barium Sulphate used in the limit test for sulphates?
Barium sulfate is used in the limit test for sulphates because it forms a highly insoluble precipitate with sulfate ions. This property allows for the qualitative or quantitative determination of sulfate ions in a sample by measuring the amount of barium sulfate precipitate formed. The formation of a white precipitate confirms the presence of sulfate ions in the sample.
