is about 150 years old‚ and today’s’ cars batteries use the original lead-acid design. Batteries have been focused on light weight and longer lasting batteries like for iPods and etc. The rechargeable battery has gone through three major changes: Nickel-Cadmium (NiCd): First used in the 1960s‚ for dry cell rechargeable batteries. But‚ cadmium is toxic and these batteries are disposed to memory effect. Like‚ if it is repeatedly charged when it is at 50 percent power‚ it will forget that it has the

the least active metal is on the right. Remember‚ sodium and copper are metals‚ too. B. Suppose you inserted a piece of copper into a solution of nickel chloride and observed no reaction. Then if you inserted a piece of iron into the solution of nickel chloride a nickel deposit formed on the bottom of the well in the well plate. Where does nickel fit into your activity series?

_______________________________________________________________________________ INTRODUCTION In aqueous solution nickel ion Ni2+ is surrounded by six water molecules which are actually bonded to the central metal ion. This complex is called the hexaquonickel(II) ion. When aqueous nickel chloride is precipitated from solution‚ the nickel ions carry their six water molecules into the crystals and so solid nickel(II) chloride is hydrated‚ has the formula [Ni(H2O)6]Cl2‚ and is more properly called hexaquonickel(II)
