The negative ion is written second in the formula for an ionic compound.
how many protons does the carbonate ion have?
Potassium ion has 18 electrons.
in one ion? one atom
It contains the sodium ion Na+ and the chlorate ion ClO3- Since sodium is the positive ion (cation) you name it first, then you name the chlorate ion second because it is the anion (negative ion). so the name of the compound is sodium chlorate.
Electrons per shell in uranium: 2, 8, 18, 32, 21, 9, 2
The chloride ion has 18 electrons.
There are 18 electrons in a chloride ion.
a cuprous ion has 28 electrons.
The ion Fr+ has 86 electrons.
CO3++ Ion has 20electrons.
1. Direct Titration In direct titration, you simply add an indicator to the solution of the metal ion and titrate with EDTA. Before starting the titration,it is needed to check that the pH of the solution to obtain a good formation constant value and on the other hand indicator colour change as well. 2.Indiract titration EDTA can be used as titrant for anions. Anions can be precipitated with suitable metal ion. Filter and wash the ppt with proper solution. Then boil in excess EDTA to complex metal ion(ppt). Back titrate to determine how much metal ion you had. 3.Back Titration In a back titration an excess of EDTA is added to the metal ion solution, and the excess EDTA is titrated with a known concentration of a second metal ion. The second metal ion must form a weaker complex with EDTA than the analyte ion so the second metal does not displace the analyte ion from its complex with EDTA. 4.Displacement titration Here the analyte is treated with an excess of a second metal bound to EDTA. The analyte ion displaces the second metal from the EDTA complex, and then the second metal is titrated with EDTA.
