Explanation:
Complexometric titration (sometimes chelatometry) is a form of volumetric analysis in which the formation of a colored complex is used to indicate the end point of a titration. Complexometric titrations are particularly useful for the determination of a mixture of different metal ions in solution.
hope it will help u ✌️
When Hexane is mixed with Water it forms a immiscible mixture. The two solvents does't make a uniform solution and create two layers.
Explanation:
Hexane is chain of six carbon atoms attached to carbon and hydrogen atoms. The molecule of hexane is non polar in nature. While water molecule is polar in nature. As LIKE DISSOLVES LIKE, so the hexane solvent being hydrophobic in nature fails to interact with hydrophilic water molecules.
The density of water is 1 g/cm³, it is heavier than Hexane with 0.66 g/cm³, so water will make the bottom layer while hexane will float on water forming the upper layer.
The new volume : V₂ = 2454.8 L
<h3>Further explanation</h3>
Given
V₁=2240 L
P₁=760 mmHg
T₁=320 K
P₂=700 mmHg
T₂=323 K
Required
Volume V₂
Solution
Combined gas law :
P₁V₁/T₁=P₂V₂/T₂
Input the value :
760 mmHg x 2240 L /320 K = 700 mmHg x V₂/323 K
V₂=(P₁V₁T₂)/P₂T₁
V₂=(760 x 2240 x 323)/(700 x 320)
V₂ = 2454.8 L
