I need help in identifying anions and cations in Chemistry?

Question

Specifically these formulas NaOH, CH3CH2OH , C3H8O, NH3 , NaOCl , NaCl, C12H22O11, CH3COOH, NaHCO3, H202, Na2C03,NaF.
Also i want to know if an atom can have multiple anions or cations for example C3H8O is it correct if I say it has one cation and two anion. Thank you

Answer 1

Na in all compounds like this is present as Na+, with the rest of the formula corresponding to an anion.

All the other examples that you give are covalent molecules, with neither cations nor anions present.

There is no reason why there should be any ions in C3H8O. So this is a very useful opportunity for you to learn; look at your reasoning again and see if you can tell what assumptions you made that are not actually correct.

Answer 2

Remember this - Cat (ion) is positive

NaOH = Na+ and OH-

ethanol or CH3CH2OH = CH3CH2O+ -H , this is actually a deprotonation

propanol or C3H8O is similar to ethanol deprotonation C3H7O+ -H

NH3 in water makes ammonium hydroxide and forms the following radicals NH4+ and OH-

NaCl = Na+ and Cl-

NaOCl = Na+ and OCl-

C12H22O11 can make too many compunds to say anything for certain. Some of them could be deprotonated

Acetic acid or CH3COOH = CH3COO- and +H

NaHCO3 = Na+ and HCO3-

Na2C03 = 2 Na+ and HCO3-

H202 = H+ and HO2-

NaF = Na+ and F-
