The answer is <span>ionic aluminum fluoride (</span>AlF3). Note that boiling points of pure solvents are raised in the presence of solutes. The type of solute also affects the boiling point elevation of the solution. Ionic substances tend to raise it more than covalent ones, so sucrose is out of the picture. Next, consider the number of ions the ionic substance produces. The more ions, the greater the BPE. AlF3 dissociates into 4 ions.
Answer:
a) 200 L of water. b) 3,2210(fifth to the power) kg
Explanation:
a) To reach toxic level of a person would have to drink 200 L of water. b) We need 3,2210 to the fifth power kg of fluride for 8,510 to the seventh power gal of water.
