Is Br2 soluble in water or carbon tetrachloride?
Is Br2 soluble in water or carbon tetrachloride?
Br2 is much more soluble in tetrachloromethane, CCl4 [aka “carbon tetrachloride”], than in water. Explain. Both bromine and CCl4 are nonpolar with dispersion forces being the only forces present. Thus, they are quite similar and “like dissolves like” prevails.
Is o2 or Br2 more soluble in water?
Both oxygen and bromine are nonpolar and exert only weak dispersion forces. Br2 is a larger molecule -> more polarizable -> susceptible to dipole -> induced dipole attractions. Click to see full answer. Bromine is slightly soluble in water (0.33 mg/mL) but it is highly soluble in organic solvents like CCl4.
Which of these substances is the most soluble in water?
Hydrochloric acid
What makes something soluble in water?
Positive is attracted to negative, making a cohesive structure. When polar compounds or ions are added to water, they break up into smaller components, or dissolve, to become part of the solution. The water’s partial charges attract different parts of the compound, making them soluble in water.
What is a good solubility in water?
Water Solubility
| Low water solubility: | less than 10 mg/L or 10 ppm1 |
|---|---|
| Moderate water solubility: | 10-1,000 mg/L or 10-1,000 ppm1 |
| High water solubility: | more than 1,000 mg/L or 1,000 ppm1 |
What does a low solubility in water mean?
solubility Add to list Share. Use the noun solubility to refer to how easily something dissolves in water or another liquid. Salt has high solubility, easily dissolving in water, while oil has low solubility in water, and sand is not at all soluble in water.
Which form of drug has greater solubility?
11. Which form of a drug has greater solubility? Explanation: Anhydrous form of a drug has a greater aqueous solubility than the hydrates. This is because the hydrates are already in interaction with the water and therefore have less energy for crystal breakup.
How co solvents increase the solubility of poorly soluble drugs?
This process is known as cosolvency, and the solvents used to increase solubility are known as cosolvent. Cosolvent system works by reducing the interfacial tension between the aqueous solution and hydrophobic solute. It is also commonly referred to as solvent blending [6].
How does pH of a solution affect solubility?
Solubility is Affected by pH If the pH of the solution is such that a particular molecule carries no net electric charge, the solute often has minimal solubility and precipitates out of the solution. The pH at which the net charge is neutral is called the isoelectric point, or pI (sometimes abbreviated to IEP).
What is the difference between fat soluble and water solubles?
The fat-soluble vitamins are A, D, E, and K. Being fat soluble means that they are absorbed in the lymph, are transported in the blood with carrier proteins, and they can be stored in the liver and fatty tissues. The water-soluble vitamins are easily dissolved and can be excreted in the urine.
How does water solubility affect drug absorption?
When delivering an active ingredient orally, it must first dissolve in gastrointestinal fluids before it can then permeate the membranes of the gastrointestinal tract to reach systemic circulation. Therefore, a drug with poor aqueous solubility will exhibit dissolution rate-limited absorption.
How can you increase the solubility of water?
Key Takeaways
- For many solids dissolved in liquid water, the solubility increases with temperature.
- The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.
What are the common injectable routes of administration?
Administration by injection (parenteral administration) includes the following routes:
- Subcutaneous (under the skin)
- Intramuscular (in a muscle)
- Intravenous (in a vein)
- Intrathecal (around the spinal cord)
