Answer:
Explanation:
Comparing to the solution consisting a pH of 5 containing 
of hydrogen ions, a solution having a pH of 6 consists of 
of hydrogen ions. A solution having a pH of 7 too will have a pH of 
.
Low pH = high acidity.
HF has a very low pH, so when added to a solution, it will lower the pH of the solution and therefore make it more acidic. So the answer should be B.
heating is repeated to ensure all water molecules have evaporated
