It's quite strong and has a weak base . it would probably dissolve and the ph would drop
4.06x20^24/6.02x10^23 = 6.744 moles x 55.845 g/mole = 376.61868grams
Answer:
there is no picture so we can't tell why the containers are heavy
D- viscosity has no effect on boiling point
<h3>
Answer</h3>
HF
<h3>Explanation</h3>
A buffer solution contains <em>a weak acid</em> and<em> its conjugate base</em>. The two species shall have a similar concentration in the solution. It's also possible for <em>a weak base</em> and <em>its conjugate acid</em> to form a buffer solution.
The KF solution already contains large number of
ions. The objective is to thus find its conjugate acid or base.
contains no proton
and is unlikely to be a conjugate acid. Assuming that
is a conjugate base. Adding one proton to
would produce its conjugate acid.

Therefore
is the conjugate acid of
.
happens to be a weak acid. As a result, combining
with
would produce a solution with large number of both the weak acid and its conjugate base, which is a buffer solution by definition.
