How do hydrogen bonds form?
|
The attraction between a slightly positive hydrogen atom and a slightly negative atom.
|
|
What are the two parts of a solution?
|
solvent
solute |
|
What does pH measure?
|
The pH measures the hydrogen concentration in a solution.
|
|
How do polar molecules form hydrogen bonds?
|
the slightly oppositely charged regions
|
|
What determines whether a compound will dissolve in water?
|
It will be determined by the ionic compounds and the polar molecules because they are both charged.
|
|
How do polar molecules differ from non-polar molecules? How does the difference affect their interactions
|
Polar molecules- form when atoms in a molecule have unequal pulls on the electrons they share.
Non-polar molecules - do not have negative or positive charged regions, they share electrons more equally. |
|
What are some properties of water?
|
High specific heat- when a large amount of energy is needed to increase the water temperature.
Cohesion- the attraction among molecules when they stick together. Adhesion- When water molecules stick to other substances. |
|
What is the difference between a solvent and a solute?
|
the solvent is the substance that is present in greater amounts and the solute is what dissolves.
|
|
What types of substances dissolve in water easily?
|
polar molecules
ionic compounds |
|
What types of substances does water not dissolve in easily?
|
Non- Polar molecules
