Correct Answer: Cation -A
Given that both the cations, cation-A and cation -B have the same concentrations.
Charge on cation-A is +3, while charge on cation- B is +1. Cations with higher charge can easily substitute those present on the clay minerals. Cations with higher charge have a greater affinity for the negatively charged sites present on the clay mineral. So, cation -A with a charge of +3 is more likely to occupy the anionic sites on the clay mineral.
Answer:
Phospholipids are carried in the blood and deposited in vital tissues such as the brain and the liver where they serve as protection to these vital organs.
Explanation:
Lipids is another name for fats. These fats play many crucial roles in the body. Phospholipids are water soluble fats. They are important in building the protective barrier, or membrane, around body cells. In blood and other body fluids, these phspholipids usually form structures that enclose fat and carry it throughout the bloodstream to the organs where they are stored in the body.
These phospholipids also play an important role of serving as a protection to vital organs in the body such as the liver and brain. Hence, a large amount of phospholipids are found in the liver and brain where they serve as protection to these vital organs.
Answer:
Zinc sulfide- more soluble in 0.10 M hydrochloric acid solution
Silver chloride- less soluble in 0.10 M hydrochloric acid solution
Lead iodide- same solubility in 0.10 M hydrochloric acid solution as in pure water
Silver hydroxide- same solubility in 0.10 M hydrochloric acid solution as in pure water
Explanation:
Solubility refers to the amount of a substance that dissolves in 1 dm^3 of solvent. Several factors influence the dissolution of solutes in a given solvent. Some substances dissolves at a low pH (in acid solutions) while other dissolve at a low pH (in basic solutions).
For Silver chloride, its solubility decreases in 0.10 M hydrochloric acid solution because of common ion effect when compared to its solubility in pure water.
