Homework Statement
I just wanted to ask why anhydrous salt is less soluble in water than hydrous salt especially in case of glauber's salt
Thank you very much!
This is because anhydrous salt does not contain water molecules in its chemical structure, whereas hydrous salt contains water molecules that are loosely bonded to the salt ions. This makes it easier for the water molecules to break the bonds between the salt ions and dissolve the hydrous salt.
Water molecules have a polar structure, with a positively charged hydrogen end and a negatively charged oxygen end. This allows them to interact with the charged ions in salts, breaking them apart and dissolving them. In hydrous salts, the water molecules are already attached to the salt ions, making it easier for them to dissolve in water.
Yes, the temperature of water does affect the solubility of anhydrous salt. As temperature increases, the kinetic energy of water molecules also increases, making them more likely to collide and break apart the salt ions. This results in higher solubility of anhydrous salt in warmer water.
No, anhydrous salt cannot become hydrous after being dissolved in water. This is because the water molecules are only loosely bonded to the salt ions in hydrous salts, whereas anhydrous salts do not contain any water molecules in their chemical structure. Once dissolved, the water molecules will remain attached to the salt ions and will not transform anhydrous salt into hydrous salt.
Yes, there are other factors that can affect the solubility of anhydrous salt. These include the size of the salt particles, the agitation of the solution, and the presence of other substances that may interact with the salt ions. These factors can all impact the ability of water molecules to break apart and dissolve anhydrous salt.
