Chemically both are same.
Pure hydrogen iodide dissolved in water is known as hydroiodic acid.
Hydroiodic acid
calcium hydroxide
Yes, it is correct.
Hydrogen.
When gaseous H2S is passed through aqueous CuSO4, a black precipitate of Copper Sulphide (CuS) is formed with sulphuric acid solution.
because when it is dissolved in water calcium hydroxide is formed
Hydroiodic Acid. It is a strong acid (100% dissociation).
calcium hydroxide
An *aqueous* solution is formed when a substance is dissolved in water. The term "aqueous" stands for the latin word "aqua" which means water.
Yes, it is correct.
aqueous
Hydrogen.
An aqueous solution is formed when a substance is dissolved in water. The latin for water is 'aqua' - hence the word 'aqueous'.A solution in which water is the primary solvent.
H+ and Cl-
When gaseous H2S is passed through aqueous CuSO4, a black precipitate of Copper Sulphide (CuS) is formed with sulphuric acid solution.
When an acid is placed in water, the hydronium ion (H3O^+) is formed.
Pb(NO3)2(aq)+2NaI(aq)=2NaNO3(aq)+PbI2(s)
Bromine is prepared by a method which comprises contacting hydrogen peroxide with an aqueous solution containing bromide ion and rapidly removing the bromine as it is formed. This method is particularly suitable for obtaining bromine from seawater, using the conventional intermediate, bromosulfuric solution.
