Saturation points of salt and sugar | Solutions | Chemistry



KClassScienceChannel

This demonstration shows that different solutes dissolve to a different extent in the same solvent. In this activity, it takes about 5 spoons of salt to make a saturated salt solution under normal temperature and pressure. By comparison, only 3 spoons of sugar are enough to make a saturated sugar solution. So we see that the saturation point of salt is higher than that of sugar. If we heat these solutions it is possible to dissolve more salt and sugar in each solution as heating increases solubility.

  1. you are a lair apparently you said you added 5 spoons of salt in the water but I was counting, you put 4 spoons of salt in the water instead you have to see the video again and if I am wrong then say how many you counted so far In your other videos

  2. So, I'm working with a softening station. It has a special vessel for preparing saturated salt water. The water level is below the level of the salt… my problem is I don't know after how long it reaches saturation. Any idea??

  3. Question! Lets say you had a mixture of salt, sand, and sugar. Then you followed these steps:
    1) Add water (20ml) to the mixture and stir until dissolved.
    2) Using a filter apparatus and a beaker, filter the salt/sugar solution from the sand.
    Would there be any way to separate the salt from the sugar?
    Please be very specific in your reply, thanks in advance!

  4. When I was a young man I had a sore throat and remember people saying I should gargle with salt water.  They usually meant a few teaspoons in a glass to gargle.  I decided I would make a supersaturated solution of salt water to gargle with and felt it would really kill the germs quickly.  Do not, I repeat do not ever do this! Fortunately I did this right over the sink and had quick access to fresh water.  I'm so glad I didn't accidentally swallow any of it.
