What effect does electroplating have on the concentration of an electrolyte?
When electroplating metal ions (e.g. Chromium) are deposited as metal at the cathode. The metal ion is reduced. The concentration of chromium ion drops as a result.
What is a metal ion?
A metal ion is an ion made out of metal. the metal ion in Na 2 S is Sodium
What is the symbol of lead iodine?
Lead iodide is not a correct name. Lead is a transition metal and can form more than one ion. The charge of the lead ion should be in the name. For example, lead(II) iodide, which would be PbI2. Lead(IV) iodide would be PbI4.
What is the charge on the lead ion in PbS2?
Lead being a transition metal has two possible charges: +2 or +4.
What is the formula for lead lV oxide?
This would be an ionic compound. The lead (IV) ion is a metal, so it would be a cation (positive ion), and the numerals tell us it has a charge of 4+. The oxygen ion is a non-metal, so it would be an anion (negative ion) and it is in group 6A, so it would have a charge of 2-.The ionic compound needs to have a net charge of zero, so we would need two oxygen ions to balance out the charge of each lead (IV) ion.Therefore, the correct formula for lead (IV) oxide is PbO2.

What is the name for the ion O2-?
O2- ion is known as peroxide in English. As it is not a transition metal ion, it is not able to be written any other way. If it were a transition metal such as Lead (Pb), the Pb4+ ion can be called lead (IV) or plumbic. Lead (IV) is written in the Stock method with roman numerals representing the electrons in the ion. Plumbic is written in the Classical method with the suffixes "ic" and "ous". As some transition metals have two different ions, "ic" is added to the higher ion name while "ous" is added to the lower ion name.

What happen to electrons when transfer to positive ions?
When an electron is tranferred to a positive (mono elementary) ion (eg. a metal ion, like Al3+) this ion is 'reduced' to an (elemental) atom (Fe). For comlex ions (eg. ammonium NH4+) it is essentially in the same way: it gets 'reduced', but not all to 'elements' (eg. 2NH4+ + 2e- --> 2NH3 + H2)

Name this binary ionic compound PbCl4 in roman numeral to indicate the chaarge on the metal ion?
Lead(IV) Chloride

An ionic bond is the attration between?
A non-metal ion and a metal ion
Is sulfate a metal?
Sulfate is a negative ion with the formula SO42- in order to balance the charge there needs to be a positive ion, which usually is a metal ion, but not always. However, the sulfate ion itself is not a metal nor does it contain a metal.
What balances charges that may build up as reduction and oxidation occur in a voltaic cell?
The Zinc metal is oxidized, while the Copper ion is reduced. The reverse reaction, the oxidation of Copper and the reduction of Zinc ion, is not spontaneous.
