Solubility is a complex and not fully understood phenomenon.
- Firstly it is explained by the type of bonds in the solute (the substance that is dissolving) compared to the type of bonds in the solvent (the substance that the solute dissolves into).
- Secondly, the existing bonds in the solute have to break and form new bonds with the solute. There has to be some 'advantage' in terms of energy for the solute to dissolve.
- In addition, the temperature will affect solubility. It is not the case that an increase in temperature always increases solubility.
- Whether there are any other dissolved substances present - 'the common ion effect'.
- Pressure can affect solubility although this is virtually insignificant when it comes to liquids and solids.

What are the factors that affect the purity of a substance?
Factors that affect the purity of a substance include the presence of impurities, the method of preparation, storage conditions, and the sensitivity of the analytical technique used for testing purity. The more impurities present, the lower the purity of the substance, which can impact its properties and performance.
Does the presence of another substance affect the rate of diffusion?
Yes, the presence of another substance can affect the rate of diffusion. Factors like the nature of the substance, concentration gradient, temperature, and molecular size can influence how quickly a substance diffuses in a system.
True or false the density of a substance is the same for all samples of substance?
False. The density of a substance can vary depending on factors such as temperature and pressure. Additionally, impurities in a sample can also affect its density.
What are three factors that affect the rate at which a substance dissolves?
Three factors that affect the rate at which a substance dissolves are temperature, surface area of the substance, and the stirring or agitation of the solution. Increasing the temperature generally increases the rate of dissolving, while breaking the substance into smaller pieces or increasing its surface area also speeds up the process. Stirring or agitation helps to bring fresh solvent into contact with the solute, enhancing the dissolving rate.
What are the factors which affect rate of diffusion?
Factors that affect the rate of diffusion include the concentration gradient (difference in concentration between two areas), temperature (higher temperature increases the kinetic energy of molecules), surface area (larger surface area allows for more molecules to diffuse), and the characteristics of the diffusing molecules (size, polarity, charge).
How does substance factors affect the rate at which a substance dissolves?

What are factors affect the solubility of a substance?
Temperature and polarity.
How does temperature affect solubility of salts?
Increasing the temperature the solubilty of salts in water is higher.
What are the factors that affect the purity of a substance?
Factors that affect the purity of a substance include the presence of impurities, the method of preparation, storage conditions, and the sensitivity of the analytical technique used for testing purity. The more impurities present, the lower the purity of the substance, which can impact its properties and performance.
How does temperature affect the solubilty of a solid in a solvent?
Usually, higher temperature = more soluble in the solvent.
What is solubility in water?
Solubility in water refers to the ability of a substance to dissolve in water and form a homogenous solution. It is influenced by factors such as temperature, pressure, and the chemical properties of the substance itself. Solubility is important in various fields including chemistry, pharmaceuticals, and environmental science.
What are the three factors that affect the solubility of substance?
Solubility of a substance is affected by pressure, type of solvent, and temperature.
Discuss the different factors that can affect the solubility of a substance?
The temperature the solvent used
How saturation affect solulubilty?
After a given concentration at a given temperature and pressure the solubilty doesn't increase by adding the solute.
Which of the following pairs of factors affects the solubility of a particular substances?
The nature of the solvent and the temperature are the main factors that affect the solubility of a substance. The solvent's polarity and ability to interact with the solute molecules, as well as the temperature of the solution, can both influence how much of a substance can dissolve.
Does the presence of another substance affect the rate of diffusion?
Yes, the presence of another substance can affect the rate of diffusion. Factors like the nature of the substance, concentration gradient, temperature, and molecular size can influence how quickly a substance diffuses in a system.
What are the factors that affect on rate of specific gravity?
The factors that affect specific gravity include temperature, pressure, and the density of the substance being measured. Temperature changes can cause the volume of a substance to expand or contract, affecting its specific gravity. Pressure changes can also alter the density of a substance, impacting its specific gravity measurement.
