Can someone please help me with this question about solubility? At 20 degrees Celsius, a saturated solution of sodium nitrate contains 100 grams of solute in 100 mL of water. How many grams of sodium chlorate must be added to saturate the solution at 50 degrees Celsius?
@wilsondanielle can you please help me?
Is that all of the information they give?
Normally you'll get a plot or something similar - solubility is a function of temperature.
i have a chart @wilsondanielle
Follow the chart and see what the solubility is at 50 degrees
for which one @wilsondanielle
I can't really help you without the chart - but you should be able to look at the solubility of the solution at 50 degrees and solve the problem
something like this https://figures.boundless.com/30840/full/solubilityvstemperature.png is what you need - where solubility is plotted against temperature
im gonna send the chart @wilsondanielle
this is the chart
@wilsondanielle
ok so sodium chlorate is NaCl. Follow the line that says "NaCl" to where it intersects with the 50 degree line - that's how many grams will dissolve in whatever mL of solution (I can't make that out - I think it's 100?)
if it's not 100mL, just cross multiply to wind up with the appropriate volume.
Also : If I'm interpreting the question correctly you need to factor in the solute from the first part.
its about 39 NaCl is the black line
