If 50g NaNO(3) is added to 100g water at 10 degrees C, how much more must be added to saturate the solution?
Do you have a graph or a table that will provide the solubility at 10o C?
To determine how much more NaNO3 must be added to saturate the solution, we need to first understand the solubility of NaNO3 in water at 10 degrees C.
One way to obtain this information is by consulting a solubility table, which provides the maximum amount of solute that can dissolve in a given quantity of solvent at a specific temperature. Alternatively, we can calculate the saturation point by comparing the initial amount of NaNO3 added to the solubility of NaNO3 in water at 10 degrees C.
In this case, let's assume that NaNO3 is fully dissolved in water at 10 degrees C and no solid remains undissolved. We can find the solubility of NaNO3 at this temperature by conducting a solubility experiment or referring to a solubility table.
Let's say the solubility of NaNO3 in water at 10 degrees C is 80g per 100g of water. This means that 80g of NaNO3 can be dissolved in 100g of water at this temperature.
If we initially add 50g of NaNO3 to 100g of water, we are still below the saturation point. To saturate the solution, we need to add enough NaNO3 to reach the solubility limit at 10 degrees C.
This can be calculated as follows:
Solubility of NaNO3 = 80g/100g
Amount of water = 100g
To find how much NaNO3 is needed to saturate the solution, we take the difference between the solubility limit and the amount already added:
Amount needed to saturate the solution = Solubility limit - Initial amount added
= 80g - 50g
= 30g
Therefore, an additional 30g of NaNO3 must be added to saturate the solution.
