Which ion has the strongest sulfonate charge?

All three ions have the same charge. What should also be apparent is that lithium is the smallest ion with the densest charge, potassium the largest with the most diffuse or fluffiest charge. We therefore might predict that the attraction of the lithium ion for the sulfonate groups in the resin is the strongest of the three ions.

Can ion exchange resins be used to deionize water?

One common use of ion exchange resins is in the deionization of water. It is useful to consider a scheme using ion exchange resins that would enable you to deionize water. If for example, we had water with sodium chloride in it (Na + Cl – ), we would need a way of removing both cations and anions.

Why is na HCl a conducting electrolyte?

The Cl – ion of the Na + Cl – would exchange with the hydroxide, converting this into sodium hydroxide (Na + OH – ), a conducting electrolyte because it stays ionized. The Cl – ion of the HCl would exchange with the hydroxide, converting this into H + and OH –, which is non-conducting water.

Which ion is more stable in water?

The larger potassium ion will be more disruptive of the hydrogen bonds, and more difficult for water to accommodate. You could then say that Li + is more stable in the water, stays in the mobile phase more, and elutes first.

Tips for Learning the Ions

a. All Group 1 Elements (alkali metals) lose one electron to form an ion with a 1+ charge b. All Group 2 Elements (alkaline earth metals) lose two electrons to form an ion with a 2+ charge c. Group 13 metals like aluminum lose three electrons to form an ion with a 3+ charge d. All Group 17 Elements (halogens) gain one electron to form an ion with a 1- charge e. All Group 16 nonmetals gain two electrons to form an ion with a 2- charge f. All Group 15 nonmetals gain three electrons to form an ion with a 3- charge Transition Metals: can form more than one ion will have their positive charge denoted by a roman numeral in parenthesis immediately next to the name of the

Polyatomic Anions

memorize the ion and vice-versa. a. sulfate is SO4

2-, so sulfite has the same charge but one less oxygen (SO3

2-) b. nitrate is NO3 -, so nitrite has the same charge but one less oxygen (NO2

2. If you know that a sufate ion is SO4

2-then to get the formula for hydrogen sulfate ion,

you add a hydrogen ion to the front of the formula. Since a hydrogen ion has a 1+ charge, the net charge on the new ion is less negative by one. a. Example:

PO4 -3 HPO4 -2 H2PO4 -

Phosphate hydrogen phosphate dihydrogen

phosphate

3. Learn the hypochlorite AE chlorite AE chlorate AE perchlorate series, and you also know

the series containing iodite/iodate as well as bromite/bromate. a. The know the other. quotesdbs_dbs12.pdfusesText_18
