Which of these saturated solutions has the lowest concentration of dissolved ions? a)nacl [aq]b)mgcl2 [aq]c)nicl2 [aq]d)agcl2 [aq]

A saturated solution of AgCl has the lowest concentration of dissolved ions.

A saturated solution is a solution that contains just as much solute as it can normally hold at a particular temperature. The solubility of a substance is defined as the amount of that substance that can dissolve in one litre of solvent.

Looking at all the options, we can see that AgCl has the lowest solubility because the salt is insoluble in water hence, a saturated solution of AgCl has the lowest concentration of dissolved ions.

D) AgCl

Step-by-step explanation:

The soubility rules state that salts containing Cl⁻ are generally soluble. An important exception is Ag⁺.

Thus, AgCl is insoluble and it has the lowest concentration of dissolved ions.

A), B), and C) are wrong, because all the compounds are soluble.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
