Stirring the solution
If you have 80 milliliters of vinegar and you add 20 milliliters of water. In this solution, water is identified as what part of solution?
The water would Beth’s solute because it is the smaller amount
Is the process of dissolving a solute in a solvent a chemical reaction or a physical reaction
Physical change because the parts never Chemical combine
Why is water describe as the universal solvent?
The unequal sharing of electrons between oxygen and hydrogen
Explain what happened to solubility when you increase the temperature
As you increase temp the solubility increases
Why is water described as a polar substance?
A positive end and a negative end
Positive charge
What most impacts whether a substance will dissolve in water?
Polarity (If it is polar it will dissolve if non polar will not dissolve
What is a PH level?
