Serggg [28]

Answer:

the funnel with the filter paper

Explanation:

When the mixture of solution is poured through the funnel with filter paper, the liquid solution can pass through the filter paper and gets collected in the beaker (filtrate) while the solid products are too large to pass through the filter paper, so they remain on the funnel (residue).

With this tool, the solid product could be separated from the mixture.

The pka of hf is 3.2 determine the pkb of hf?
Julli [10]

Well, first we must remember that

pK_{a}+pK_{b}=14

This is because

K_{a}*K_{b}=10^{-14}

-log(K_{a}*K_{b})=-log(10^{-14})\\-logK_{a}+-logK_{b}=-log(10^{-14})\\pK_{a}+pK_{b}=14

So then

pK_{b}=14-pK_{a}=14-3.2=1.8
