Normally, if the difference in electronegativity is larger than 1.7, then it is more ionic than covalent; equals 1.7, 50% covalent 50% ionic; smaller than 1.7, more covalent than ionic. Thus, you can also use this as a guideline to judge whether a binary compound (like NaCl) is ionic ...
The solubility of a compound in a particular solvent says so much about the interaction to which the solute and the solvent will have. If the interaction between the two is favorable then the solubility of the solute in that solvent is high. The opposite is true when the interaction is ...
In the preceding figure, we can see what happens when we place carbon tetrachloride into water. Because carbon tetrachloride is a nonpolar molecule, the interactions between adjacent molecules are very weak. As a result, we might expect carbon tetrachloride to be very soluble in water. However, ...
and, as is so common with failures in the lab, he ended up with a nasty, black solid residue in the bottom of his flask. While cleaning the flask, he found that the mess contained a purple-colored compound tha...
Plants contain a lot of cellulose, an organic compound that helps keep plant cell walls stiff. Cellulose is great at absorbing water, which is why we make towels out of cotton instead of polyester. Water molecules cling to cellulose and climb along it through a process called capillary action...
If your compound is soluble in an organic solvent which is immiscible with water, the best way to get rid of DMSO is to dilute the hell out of the sample with water and do repeated extractions with solvent. Check with TLC to make sure you've got it all. If you're lucky the DMSO ...
Knowing how to remove chemicals from water is an essential skill that might come in handy if the tap water becomes undrinkable. Think of any disaster scenario, chemical spill, or hurricane, and there is a run on bottled water at the supermarkets. Learning to purify water is even more critica...
Alright? Now for the last 2, like I said, you are going to have to draw proper Lewis structures in order to know if it has its dipole or not. Okay? Because it can get a little tricky if you don't draw the Lewis structure.Show more An aqueous solution is one with wate...
Transitioning to water management, alum serves an equally important role as a clarifier. According toHAB Aquatic Solutions“Alum is [also] harmless to plants. In fact, the improved water clarity after an alum application typically results in an increase of aquatic plants in the lake.” ...
Elements like seed protein and soluble carbohydrates in the ISS seedlings existed at different levels than those of the ground control group. Researchers noted this might change the taste of space-grown food. It's important to note, however, that the mixed results may be explained because of ...
