answer 1-4
Which of the following (a-d) is TRUE regarding solid NaCl dissolving in water The attraction of the water to the ions in NaCl is through dipole-dipole IFs. Water is considered the solute and NaCl the solvent. The partially positive oxygen in water is attracted to the chloride ion. d. The process of separating the sodium ions from the chloride ions is endothermic. All of these statements are true. polar For the following solution, describe the deviation with respect...
