To answer the question about how stirring affects the solubility of a gas in a liquid, we need to understand the process of dissolving. When a gas dissolves in a liquid, it forms a solution by mixing with the liquid molecules. Stirring helps by increasing the contact between the gas and the liquid, allowing more gas molecules to come into contact with the liquid molecules. This increased contact and mixing lead to faster dissolution of the gas, so the solubility of the gas increases when the mixture is stirred. Therefore, the correct answer is that the solubility of a gas in a liquid speeds up when the gas-liquid mixture is stirred.
For the question about the effect of pressure on the solubility of a gas in a liquid, it is important to note that gases are more soluble at higher pressures. When the pressure is increased, more gas molecules are forced into the liquid, resulting in a higher concentration of dissolved gas. As a result, the solubility of a gas in a liquid is higher under high pressure conditions. Therefore, the correct answer is that a gas's solubility is higher in a liquid when under high pressure.
To compare the methods of speeding up the rate of solution for dissolving a solid in a liquid with the methods for dissolving a gas in a liquid, we can consider the differences between the two processes.
When dissolving a solid in a liquid, factors like temperature, surface area, and stirring can affect the rate of dissolution. Increasing the temperature generally speeds up the process, as it provides more energy for the solid particles to break apart and mix with the liquid. Increasing the surface area, either by crushing the solid into smaller pieces or using a powdered form, also increases the rate of dissolution by exposing more solid particles to the liquid. Lastly, stirring the mixture helps by allowing for greater contact between the solid and liquid, enhancing the mixing and dissolution process.
On the other hand, improving the rate of solution for dissolving a gas in a liquid is primarily dependent on pressure and temperature. As mentioned earlier, increasing the pressure increases the solubility of the gas, leading to a faster rate of solution. Higher temperatures also aid in faster dissolution, as they increase the kinetic energy of both the gas and liquid particles, making them move more vigorously and facilitating their mixing.
Lastly, for the question of whether amalgams are a solution, the answer is yes. An amalgam refers to a mixture of a metal, usually mercury, with one or more other metals. The metal being dissolved (solute) is usually present in a smaller amount, while the solvent, mercury, is present in a larger amount. This combination forms a homogeneous mixture or solution. Therefore, an amalgam can be considered a solution.
