Table salt has a solubility of 36 g of salt in 100 g of water at 40°C. If 15 g of the salt are added to 50 g of water at the same temperature, is the resulting solution saturated or unsaturated? Explain your answer.
The resulting solution is saturated because 86 is what equals both of the grams of salt added to the water at degrees C. 15 g + 50 g = 86 grams
15g salt/50 g is equivalent to 30gsalt/100gwater.
so is that above, or below the saturated level?
I am really confused on this too. I'm pretty sure you come from Connections Academy. What I did was gon on google and search saturated and unsaturated. It should help a bit?
To determine if the resulting solution is saturated or unsaturated, we need to compare the amount of salt that actually dissolves with the maximum amount of salt that can dissolve at the given temperature.
First, let's find out how much salt can dissolve in 50 g of water at 40°C. We can use the given solubility value:
Solubility of salt = 36 g of salt per 100 g of water
Let's calculate the maximum amount of salt that can dissolve in 50 g of water:
(36 g / 100 g) × 50 g = 18 g
So, in 50 g of water at 40°C, the maximum amount of salt that can dissolve is 18 g.
Now, let's compare this with the actual amount of salt added to the water, which is 15 g.
Since the actual amount of salt added (15 g) is less than the maximum amount that can dissolve (18 g), the resulting solution is unsaturated. This means that some of the salt will dissolve in the water, but there will still be some undissolved salt present.
In summary, the resulting solution is unsaturated because the amount of salt added is lower than the maximum amount that can dissolve at 40°C.
