Study Notes
Volumetric Analysis
- Determining the concentration of a substance by measuring the volume of a solution of known concentration that reacts completely with it.
Titrimetry Reactions
- Refer to the types of chemical reactions that occur during titration.
- Common types include neutralization, precipitation, and redox reactions.
Dissociation, K-Value, and Acid/Base Strength
- Strong acids and bases dissociate almost completely in water, leading to a high K value.
- Weak acids and bases dissociate partially in water, resulting in a low K value.
Quantitative Reaction Requirement
- The reaction must proceed to completion, meaning that the reactants are completely consumed, in order to ensure accurate results in volumetric analysis.
pH Computation
- A calculator is used to compute pH from hydrogen ion concentrations and vice versa for easier and accurate calculations.
Collecting Wild Medicinal Plants - Disadvantage
- Can lead to overharvesting and depletion of plant populations.
Cultivating Medicinal Plants - Advantage
- Provides a sustainable and controlled source of medicinal plants, mitigating overharvesting of wild populations.
Transportation of Wild Plants - Difficulty
- Plants are often found in remote or inaccessible areas, making transportation challenging for wild populations.
Unskilled Personnel and Improper Collection
- Lack of knowledge and training can result in the collection of incorrect plants or the harvesting of plants at inappropriate times.
Cultivating Medicinal Plants - Improvement
- Cultivation allows for controlled conditions optimized for growth, resulting in higher quality, consistent, and potentially more potent medicinal plants.
