A non-hydrated ion is an ion that exists in a solvent without water molecules attached, while a hydrated ion is an ion surrounded by water molecules forming a hydrated sphere. The presence of ...
An experiment in a general chemistry laboratory calls for a 2.00-M solution of HCl. How many mL of 11.9 M HCl would be required to make 250 mL of 2.00 M HCl? A solution is formed by mixing 1 gal ethanol with 10 gal gasoline. Identify the solvent and the solute. An experiment calls for 100. mL of 1.25 M HC1.
The ion with 52 protons, 76 neutrons, and 54 electrons is the ion of element tellurium (Te) with a charge of +2. The number of protons determines the element, the number of neutrons can vary in ...
Chemistry. While preparing a 0.200 M carbonate ion solution, you added DI water to the 100.00 mL volumetric flask, but you went over the mark by a visible amount. Show calculations; and include a typed an explanation to describe your reasoning. (Show a calculation that finds the concentration from the mass with the correct volume and another ...
SO4-2The sulfate ion is a polyatomic ion made up of one sulfur atom and four oxygen atoms, that exists only if it can gain 2 electrons (from some metal cation or cations). It has a charge of -2.
An ion of copper, Cu+2, has 27 electrons and a charge of +2.The copper atom has loaned out (or had borrowed from it) in a chemical reaction, those 2 electrons. An ion is formed any time the number ...
Its chemical symbol is Al3+. The name of an aluminum ion is simply aluminum ion. It most commonly forms a compounds in the +3 oxidation state but can also be found in +2 and +1. bauxite. The ...
A sodium ion has a charge of 1+ because it has lost one electron, leaving it with one more proton than electrons. Protons have a positive charge, whereas electrons have a negative charge, so ...
