Suppose a saturated solution of this solute was made using 85.0 g H 2 O at 20.0 °C. How much more solute can be added if the temperature is increased to 30.0 ∘ C?

This is an incomplete question, here is a complete question.

Here are the solubilities of a particular solute of two different temperatures:

Temperature (°C)         Solubility (g/100 g H₂O)

20.0                                               28.4

30.0                                               76.5

Suppose that you have made a saturated solution of this solute using 85.0 g of water at 20.0 °C. How much more solute can you add if the temperature is increased to 30.0 °C. (PLEASE explain in detail & answer in grams)

Answer : The more amount of solute added can be, 40.885 grams.

Explanation :

First we have to calculate the amount of solute at 20.0 °C.

As, 100 g of water contains amount of solute = 28.4 g

So, 85.0 g of water contains amount of solute =

Now we have to calculate the amount of solute at 30.0 °C.

As, 100 g of water contains amount of solute = 76.5 g

So, 85.0 g of water contains amount of solute =

Now we have to calculate the more amount of solute can be added.

Amount of solute added = 65.025 g - 24.14 g

Amount of solute added = 40.885 g

Thus, the more amount of solute added can be, 40.885 grams.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
