    Solvent Sugar
AI Thread Summary
Wine acts as a solvent due to its composition, primarily being a solution of water and ethanol, which are completely miscible and can mix in any proportion. In contrast, sugar is a solid and functions as a solute when dissolved in water, which serves as the solvent. The concept of solubility is key, as it defines how much solute can dissolve in a solvent. A solution is characterized by the presence of both a solvent and a solute, which can be gases, liquids, or solids of different chemical compositions.

Uh ... because sugar is a solid ?
 
Wine is a solution of water and ethanol plus some other chemical compounds. In this case they are toally miscible, meaning that they can mix in all proportion.

Sugar can dissolve in water, and here we can describe how much by the term solubility.
Sugar would be the solute and water the solvent.

Technically, a solution contains a solvent ( gas, liquid or solid ) and a solute ( gas, liquid or solid of different chemical ).
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
