The sedimentation rates of CuS and BaS were determined by measuring the % transmittance with time of the metal sulphide precipitates in aqueous media.

Active 5 years ago. Browse other questions tagged acid-base equilibrium or ask your own question. Rule 1 states that all compounds with NH4+ are soluble, so NH4Cl is aqueous. BaSO4 has a Ba 2+ ion and a SO4 2- ion. Rule 3 states that compounds with SO4 2- ions are soluble except when paired How do you tell if a compound is solid, liquid, gas, or aqueous? Aside from looking at?

Over time one becomes familiar with certain substances.

HF, HCl, HI, and HBr are gases. As you go down the periodic table (as the atoms get heavier), the elements and compounds of them generally (but not always) have higher melting and boiling points.

Adding Ba++ ions would increase the barium ion concetration even if some precipitates. The correct answer comes from the "common ion effect". Consider the equilibirum BaSO4 (s) <==> Ba++ + SO4= According to LeChatelier's principle adding Ba++ 2018-09-19 · A precipitate is a compound with a low solubility that often falls out of solution as a solid. The terms acid, base, and pH only apply to aqueous solutions. For example, you can measure the pH of lemon juice or vinegar (two aqueous solutions) and they are weak acids, but you can't obtain any meaningful information from testing vegetable oil with pH paper. As you can see, it is critical to include the symbols for each species to identify what state they're in: either gaseous (g), solid (s), liquid (l) or aqueous (aq).

As you can see, it is critical to include the symbols for each species to identify what state they're in: either gaseous (g), solid (s), liquid (l) or aqueous (aq). It is also important to remember that these types of ionic equations also must have a balanced charge. 2019-09-11 · Examples of solutions that are not aqueous solutions include any liquid that does not contain water. Vegetable oil, toluene, acetone, carbon tetrachloride, and solutions made using these solvents are not aqueous solutions. Similarly, if a mixture contains water but no solute dissolves in the water as a solvent, an aqueous solution is not formed.

Substances that dissolve in water can be categorized according to whether the resulting aqueous solutions conduct electricity. Strong electrolytes dissociate completely into ions to produce solutions that conduct electricity well.
