which of the following compounds dissolve in water??
-Sodium Nitrate (NaNO3)
- Sucrose (C12H22O11)
- Sodium Chloride (NaCl)
- Potassium Sulfate (K2SO4)
- Ethanol (C2H5OH)
- Sodium Bicarbonate (Baking Soda)(NaHCO3)
- Calcium Sulfate (CaSO4)
i did an experiment, but I was not able to confirm whether or not they dissolved in the distilled water. Please help!
How can you do an experiment and not know if something dissolved or not? Calcium sulfate is the only one that is not VERY soluble. And calcium sulfate is not nearly as insoluble as many compounds.
we only used small samples and for most of the compunds they just stuck to the bottom. So are you saying that calsium sulfate is the only one that doesn't disolve?
Yes, all of the others are freely soluble.Put some sugar in a glass of water, stir, and see if it doesn't dissolve relatively rapidly. Do the same for table salt. They will NOT stick to the bottom. If your samples stuck to the bottom of the test tube, it's because they weren't stirred properly.
ok thank you
To determine whether the compounds listed will dissolve in water, you can consider their solubility properties.
First, let's define solubility: It refers to the ability of a substance (solute) to dissolve in another substance (solvent) to form a homogeneous mixture. When a substance dissolves in water, it forms an aqueous solution.
Here are the solubility properties of the compounds listed:
- Sodium Nitrate (NaNO3): Sodium Nitrate is highly soluble in water. It readily dissolves in water, forming an aqueous solution.
- Sucrose (C12H22O11): Sucrose is also highly soluble in water. It readily dissolves in water, forming an aqueous solution.
- Sodium Chloride (NaCl): Sodium Chloride is very soluble in water. It readily dissolves in water, forming an aqueous solution.
- Potassium Sulfate (K2SO4): Potassium Sulfate is highly soluble in water. It readily dissolves in water, forming an aqueous solution.
- Ethanol (C2H5OH): Ethanol is partially soluble in water. It can form a homogeneous mixture with water, but its solubility depends on the concentration. At lower concentrations, ethanol is completely miscible (fully soluble) in water.
- Sodium Bicarbonate (Baking Soda)(NaHCO3): Sodium Bicarbonate is moderately soluble in water. It dissolves in water, but its solubility is limited compared to the previously mentioned compounds.
- Calcium Sulfate (CaSO4): Calcium Sulfate has low solubility in water. It doesn't readily dissolve in water, and its solubility is quite limited.
Regarding your experiment, if you were not able to confirm whether the compounds dissolved in distilled water, try repeating the experiment using smaller amounts of the compounds and increasing the stirring time. Also, make sure the water is at room temperature, as some compounds may have temperature-dependent solubilities.
If you need further confirmation, you can search for solubility tables or consult reliable sources that provide solubility data for specific compounds.
