Question 1

In titrating 0.20 M hydrochloric acid, HCl, with 0.20 M NaOH at 25°C, the solution at the equivalence point is

0.20 M NaCl
very acidic
slightly acidic
0.10 M HCl and 0.20 M NaOH
0.10 M NaCl

Question 2

In titrating 100 mL of 0.10 M HCl (aq) with 0.10 M NaOH, the pH does not change a great deal initially. Why is this?

The amount of OHhas no effect on the pH of aqueous solutions.
The H+ from the HCl (aq) acts like a buffer.
The major species when the acid and base are mixed form a buffered solution.
The statement “In titrating 100 mL of 0.10 M HCl (aq) with 0.10 M NaOH, the pH does not change a great deal initially.” is not true.
None of these are correct.

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.
