In the solubility lab, sugar was the _____________ and water was the _______________.
Rasek [7]

In a homogenous mixture, sugar was the solute and water was the solvent. Solubility is the maximum amount of a solute that dissolves in a given amount of solvent at a constant temperature. Solutes are more soluble in a given solvent at higher temperatures. Therefore, when temperature increases, the solubility of the solute also increases.

<span>Moreover, the solubility of the substance ranges from infinitely soluble such as alcohol in water, to poorly soluble like silver chloride in water and the species that dissolves, the solute, can be another liquid, gas or a solid.</span>

To what temperature must a sample of nitrogen at 27°C and 0.625 atm be taken so that it’s pressure becomes 1.125 atm at constant
Karo-lina-s [1.5K]

Answer:

The sample of nitrogen must be taken to 267 ^{0}\textrm{C}.

Explanation:

Let's assume nitrogen gas behaves ideally.

Here amount of nitrogen gas in both states remain constant.

So, in accordance with combined gas law for a given amount of an ideal gas in two different states:            \frac{P_{1}V_{1}}{T_{1}}=\frac{P_{2}V_{2}}{T_{2}}

where P_{1} and P_{2} are initial and final pressure respectively. V_{1} and V_{2} are initial and final volume respectively. T_{1} and T_{2} are initial and final temperature (in kelvin scale) respectively.

Here V_{1}=V_{2} , P_{1}=0.625atm , T_{1}=(273+27)K=300K and P_{2}=1.125atm

So T_{2}=\frac{P_{2}T_{1}}{P_{1}}=\frac{(1.125atm)\times (300K)}{(0.625atm)}=540K

540 K = (540-273) ^{0}\textrm{C} = 267 ^{0}\textrm{C}

So the sample of nitrogen must be taken to 267 ^{0}\textrm{C}.
