Calcium chloride (CaCl2) absorbs moisture from the air effectively. It can attract several times its own weight in water, dissolving into a liquid brine if the air is humid enough and the temperature is high enough. The liquid brine is either trapped inside a collector or mixed with a modifi...
In reality, I think the basic pH of 8-9 that can be observed when CaCl2 is added to solution probably arises in a complex way. For example, after dissolving calcium chloride in water it can form calcium hydroxide as shown by blue ray above. Calcium hydroxide can further react with CO2 i...
Will the given solid compound dissolve in water? Why or why not? PbO2 Explain why benzophenone is more soluble in acetate than in water. Explain why calcium sulfate is less soluble in sodium sulfate solution than in pure water. Explain why non-ionic compounds, such as ethanol or sugar, are...

Why is water known as a universal solvent? Why do some substances not dissolve in water at all? Why should solutes be added to water rather than water added to solutes? Why does sugar dissolve well in water? Why do salts dissolve in water?
Is ethanol a deliquescent? Hygroscopic substances include honey, glycerin, ethanol, methanol, concentrated sulfuric acid, and concentrated sodium hydroxide (lye). Calcium chloride is so hygroscopic that it eventually dissolves in the water it absorbs: this property is called deliquescence (see below)....
no fish either. This is because the Dead Sea is nearly six times as salty as the ocean. It also contains many other dissolved minerals, including magnesium chloride, calcium chloride and potassium chloride in large quantities. Whereas in fresh water, only minute quantities of these minerals are...
L-Lysine is a configuration of lysine, and only the L-form of lysine can be utilized by living organisms. L-Lysine has a molecular weight of 182.65 and is a white or nearly white crystalline powder with a free-flowing nature and almost no odor. It is soluble in water and formic acid,...
Why does benzoyl chloride react preferentially with an amine rather than Na2CO3 or water? Why is diamond so hard to break? Explain why acetals do not react with nucleophiles? Why is HBr/KBr not a buffer solution? Why is it important to maintain the correct proportions of reagents in the Al...
