The ability for a substance to dissolve in a solvent
3 things that increase the rate of solubility

The water because there’s less of it
The the process of dissolving a substance a chemical change or physical
Physical change because the parts never chemically combined
Why is water the universal solvent
The unequal sharing of electrons between oxygen and hydrogen
What happens to the solubility when you increase the temp
The solubility increases
Why is water a polar substance
A positive end and a negative end positive charge
What most impacts whether a substance will dissolve in water
Polarity
What is ph level
Measure of how acidic or basic
Give examples of an acid
Taste sour react with metals ph 0-6
What happens when you combine a acid and base
Neutralization
What is neutral ph
Ph of 7
