Question
If some salt accidentally spilled as it was transferred from the balance to the cup would your calculated enthalpy of solution of the salt be too high or too low explain
Solution
If some salt accidentally spilled as it was transferred from the balance to the cup, your calculated enthalpy of solution of the salt would be too high. Here's why:
-
The enthalpy of solution is calculated based on the amount of salt that is assumed to have dissolved in the solution. This is usually determined by the weight of the salt measured on the balance.
-
If some salt spills while being transferred, the actual amount of salt that ends up in the solution is less than what was measured on the balance.
-
However, when you calculate the enthalpy of solution, you would still be using the original, larger weight measured on the balance (since you wouldn't know some salt had spilled).
-
This would make it seem like more salt had dissolved in the solution than actually did, leading to a higher calculated enthalpy of solution.
-
In reality, because less salt dissolved, the enthalpy of solution should be lower. So, the calculated value would be too high compared to the actual value.

You are tasked to determine the effect of temperature on the rate of dissolution of salt in water. So you dissolved 10 grams of salt by pouring it into the water, then immediately stirred the solution clockwise 3 times. You then time how long it will take for the salt to disappear in the water completely. The data table below summarizes your experiment. If you increase the amount of salt to 20 grams and do the experiment again, what do you think will be the effect of temperature on the rate of dissolution for this scenario?a.the colder the water, the faster the salt dissolvesb.the colder the water, the more grams of salt can be dissolvedc.the hotter the water, the faster the salt dissolvesd.the hotter the water, the more grams of salt can be dissolved
