The conductivity would decrease because the concentration of ions decreases.

As barium hydroxide, a solution is added to sulphuric acid, the Barium ions replace the hydrogen ions to form a precipitate. An insoluble solid doesn't contribute ions and as such the forming of the solid barium hydroxide would mean a decrease in the concentration of the ions.

balu736 [363]

Answer:

25.0 g.

Explanation:

From the solubility curve that is shown in the attached image, the solubility of KCl per 100.0 g of water is about 50.0 g.

<em>So, a saturated solution of KCl in 50.0 g of water will contain about 25.0 g.</em>

<em>Thus, the grams of the dry salt that will be recovered is 25.0 g.</em>
