Pure water is a poor conductor of electricity. when sodium chloride (nacl) is dissolved in water, however, the solution becomes a good conductor of electricity. which of the following statements explains this change in conductivity?
a. the nacl dissociates into na+ and cl- ions, which are able to carry the charge. b. the nacl breaks down the water molecules creating charged oxygen and hydrogen ions.
c. the nacl molecule changes and becomes a covalent bond when dissolved in water.
d. the nacl reacts with water to form the electrically charged compounds hcl and na2o.

If i can still dissolve more sugar into the solution at a certain temperature what would i call that solution

Many reactions take place in aqueous solution. when potential reactants are mixed, a reaction will occur if there is some driving force that favors the formation of products. it is often convenient to categorize reactions in terms of these driving forces: precipitate formation, in which an insoluble solid is formed, weak electrolyte formation, as in a neutralization reaction involving water, or transfer of electrons, as in a redox reaction. these reactions can be represented by full molecular equations, which contain all species in the reaction mixture, or by net ionic equations, which show only the species that actually undergo a change. the latter does not contain the spectator ions, which do not undergo a net change or do not take part in the reaction. part a when the following two solutions are mixed: k2co3(aq)+fe(no3)3(aq) the mixture contains the ions listed below. sort these species into spectator ions and ions that react. drag the appropriate items to their respective bins. view available hint(s) spectator ions ions that react part b what is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? assume that the contribution of protons from h2so4 is near 100 %.ba(oh)2(aq)+h2so4(aq)→ express your answer as a chemical equation. view available hint(s) nothing provide feedback
