vocabulary for aqueous solutions P1
Term | Definition |
---|---|
Solute | The substance that gets dissolved in a solution |
Solution | A homogeneous mixture made of a of solute and a solvent |
Solvent | The part of a solution that does the dissolving. In aqueous solutions, the solvent is water |
adhesion | the attraction between water and a different substance |
cohesion | the attraction between identical molecules (for example, between 2 water molecules) |
Dissociation | The formation of ions that occurs when an ionic compound breaks apart in water |
Dissolving | The separation of the particles in a substance when placed in water, making them no longer visible to the eye. The particles spread out in the water. |
Polar Molecule | A molecule that has an uneven distribution of electrons. It has a partial negative side and a partial positive side. |
Water's Polarity | The oxygen side has a partial negative charge and the hydrogen side has a partial positive charge |
Hydrogen Bonding | Water molecules cling to each other due to the polarity of the molecule |
non polar molecule | molecule that shares electrons equally and does not have oppositely charged ends |
ionic compound | Compound composed of opposite charged ions; typically dissolve well in water |
water | A molecule made of one oxygen and two hydrogen atoms held together by covalent bonds |
covalent bond | A chemical bond formed when two atoms share electrons |
partial charge | an imbalance in the sharing of electrons creates this type of charge |
