What effect will dissolving larger amounts of salt in a beaker of water have on the concentration and conductivity of the solution?
1. The concentration does not change, but the conductivity increases.
2. Both concentration and conductivity decrease.
3. Both concentration and conductivity increase.
4. The concentration increases, but the conductivity does not change.
Both concentration and conductivity increase.
Ryan is wrong, there are two similar questions and D is the answer to the other question.
To determine the effect of dissolving larger amounts of salt in a beaker of water on the concentration and conductivity of the solution, we need to understand the basic concepts of concentration and conductivity.
1. Concentration: Concentration refers to the amount of solute (in this case, salt) dissolved in a given amount of solvent (water). It is usually expressed in terms of molarity (moles of solute per liter of solvent).
2. Conductivity: Conductivity is a measure of how well a solution can conduct electricity. It is influenced by the presence of ions in the solution, which are formed when a solute (like salt) dissolves and dissociates into its respective ions.
Now, let's analyze the options given:
1. The concentration does not change, but the conductivity increases.
This option suggests that the amount of salt dissolved remains the same while the conductivity increases. This isn't correct since increased conductivity is typically a result of increased ion concentration, meaning that the concentration would have to increase as well.
2. Both concentration and conductivity decrease.
This option suggests that both the concentration of salt and the conductivity of the solution decrease when more salt is added. This isn't correct because adding more salt to the solution would generally increase both the concentration and conductivity.
3. Both concentration and conductivity increase.
This option suggests that both the concentration and conductivity increase when more salt is added. This is the correct answer. When more salt is added to the water, the concentration of the salt in the solution increases, resulting in a higher number of ions available to conduct electricity. As a result, the conductivity of the solution increases.
4. The concentration increases, but the conductivity does not change.
This option suggests that the concentration of salt in the solution increases but the conductivity does not change. This is not correct since increased concentration typically leads to an increase in conductivity.
So, the correct answer is option 3: Both concentration and conductivity increase.
