Do all substances dissolve? - Coggle Diagram
Do all substances dissolve?
What are some of the factors that may affect the solubility of a substance?
What difference in polarity is there? Can extremely polar substances dissolve semi-polar substances?
partially dissolvable substances are usually dissolvable by exptremely polar substances, due to their extreme dipoles being very attractive towards each other.
Is there a point of which a chemical has too big of a molar mass to dissolve, such as wood, etc.
Most chemicals are dissolvable, for example wood, despite being a complex molecule, can be dissolved through extremely hot solvents such as lava. However, wood inhibits an extremely large amount of water, making it have a polar and non-polar structure.
Unfortunately, this 'dissolving' is rather the breaking of chemical bonds between the organic molecules, which then allow the solute to travel within the solvent.
Collison theory (temperature, concentration, etc.)
What substances? Organic, Ionic, Covalent?
How will we measure?
What variables are there?
How will it be a fair test?
Can we dissolve all substances?
Are the equipment suitable to dissolve all the substances in the world?
Can non polar substances dissolve polar substances with a small molar mass?
Can a mixture of both polar and non polar (e.g, soap) be dissolved easily?
Yes, but a two-step process may have to be made to dissolve
Are all substances obtainable?
Are there any limitations within the school lab?
Can the question be answered without the presence of all solutes?
Do we have access to all the solvents?
Is the solvent polar or non-polar? Does it include excessive heat or a higher concentration that could possibly allow all molecules to be dissolved?
For a solute to be dissolved, the solvent must have a similar polarity (like dissolves like), which allows the electronegative element in the molecule to attract the element with the slightly positive dipole.
Is water itself soluable?
Does the solvent have to be water?
How will the molecular size of different solids affect their solubility?
Is it purely based on secondary forces?
Yes, as solubility is a physical property
What will be the solvent? What will be the solute?
Are they going to be in solid form or liquid form?
