Water Chemistry

3. require a greater change in energy to change their temperature
9. has a region with a slightly positive charge, and a region with a slightly negative charge
12. mixture of substances that is the same substance
13. substance that is dissolved
14. H2O sticks together
15. Higher than pH of 7
16. water makes this structure when it forms ice

1. measurement of how acidic or basic something is
2. When Hydrogen with particle positive charges bond with partial negative charges
4. the movement of water through a porous material or narrow space against gravity due to the forces of adhesion, cohesion, and surface tension
5. Hydrogen bonds hold H2O molecules together so tightly that the water’s surface acts like a membrane
6. these bonds occur when electrons are shared unequally between two atoms, creating regions of positive and negative charge in the molecule. The molecule takes on a triangular shape.
7. has no charges
8. Lower than pH of 7
10. substance that dissolves another substance
11. H2O sticks to others
