Study Notes
Solutes, Solvents, and Solutions
- A solution consists of a solvent (the substance that does the dissolving) and a solute (the substance being dissolved)
- The solvent is the substance that is present in a larger amount, and the solute is the substance present in a smaller amount
- In a solution, the solvent and solute are mixed homogeneously, meaning they are evenly distributed
Diffusion
- Diffusion is the process of particles moving from an area of higher concentration to an area of lower concentration, resulting in uniform distribution
- Diffusion occurs due to the random motion of particles, causing them to spread out and become evenly distributed
- No energy input is required for diffusion to occur, as it is a natural process driven by the particles' kinetic energy
Concentration and Solution Terminology
- A hypertonic solution is a solution with a high concentration of solute
- A hypotonic solution is a solution with a low concentration of solute
- Osmosis is the diffusion of water as a solvent through a semi-permeable membrane, typically from a hypotonic solution to a hypertonic solution
Semi-Permeable Membranes
- A semi-permeable membrane allows certain particles to pass through, while blocking others
- In the context of osmosis, a semi-permeable membrane allows water molecules to pass through, but blocks the passage of solute molecules
- This results in water molecules flowing into the hypertonic solution, causing the concentration of solute to decrease and the concentration of water to increase
Osmosis
- Osmosis is an important biological process that helps to maintain cellular equilibrium
- Osmosis occurs when a semi-permeable membrane separates two solutions with different concentrations of solute
- Water molecules flow into the hypertonic solution, causing the cell to swell, and potentially leading to cell lysis if the cell membrane is not strong enough to withstand the pressure.
