Question

Which of these constituents of an aqueous solution can transmit charge in a current? (Choose at least one answer.)

chloride ions

sodium atoms

acetic acid molecules

water molecules

electrons protons

sodium ions

hydroxide ions

acetate ions

Answer 1

Ions are likely to transit charge in a current

they must be cation/anions

knowing this:

chloride ions --> will do, Cl- is an anion

sodium atoms --> false, Na must be charged

acetic acid molecules --> False, this is molecular, no cation/anion charge

water molecules --> false, this is polar solvent, no caiton/anions

electrons protons -> electrons have charge per se

sodium ions --> will do similar to Cl-

hydroxide ions --> will do, if in high concentration

acetate ions --> will do, since it is a anion
