In this experiment you will column filled with an ion exchange resin to swap the copper ions from an unknown solution of copper(ii) nitrate with hydrogen ions. this will produce solution of nitric acid, hno,, which can then be analyzed via a traditional acid-base titration. 2 hno, + cu2-ion exchange resin use a a cu(no)22h-ion exchange resin knowing the concentration of nitric acid from your titration you will be able to calculate the concentration of copper(ii) nitrate in the unknown solution you are analyzing.

possibly, yes.

explanation:

the amount of sugar you take in is dangerously high, risk of heart disease, high risk of diabetes, and etc.

i do not get it   at all

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
