Question

please review this multimedia presentation and then answer the question. salt dissolves in water https://mediaplayer.pearsoncmg.com/assets/secs-es-animation-salt_dissolves_in_water when water interacts with salt the salt molecule is broken apart and dissolves because: (select all that are correct) the positive ends of the water molecule attract the positively charged sodium ions the negative ends of the water molecule attract the negatively charged chloride ions the negative ends of the water molecule attract the positively charged sodium ions the positive ends of the water molecule attract the negatively charged chloride ions.

Explanation:

Water is a polar molecule. The oxygen - rich end of the water molecule has a partial negative charge and the hydrogen - rich end has a partial positive charge. Salt (sodium chloride) is an ionic compound with positively charged sodium ions ($Na^+$) and negatively charged chloride ions ($Cl^-$). Opposite charges attract. So, the negative ends of water molecules attract the positively charged sodium ions and the positive ends of water molecules attract the negatively charged chloride ions, which helps in dissolving salt in water.

Answer:

C. The negative ends of the water molecule attract the positively charged sodium ions
D. The positive ends of the water molecule attract the negatively charged chloride ions
