Lithium batteries are used throughout our modern world – in cell phones, laptops, tablets, etc. In fact, if you are regularly recharging your device, it’s highly likely it contains a lithium ion battery. The lithium iron phosphate battery provides stable function over time. The overall reaction for the lithium iron phosphate battery is below: LiFePO4 + 6 C -> LiC6 + FePO4 A certain lithium battery weighs 0.6 g and has a capacity of 2250. mA hr (that is, the cell can store charge equivalent to a current of 2250. mA flowing for 1 hr). What is the capacity of this cell in coulombs? What mass of the reactants is needed to deliver 2250. mA hr? What percentage of the cell mass consists of reactants?

The solution being added is called the titrant, and we say that it solution. The completion of the reaction is usually shown by a change of color caused by a substance called an indicator. used titrate the other A typical titration proceeds in the following way. A specific volume of the solution to be titrated is poured into an Erlenmeyer flask. For example, 15.0 mL of a sulfuric acid solution of unknown concentration is added to a 250 mL Erlenmeyer flask. An indicator is then added to the flask, which changes color when the reaction is complete. The titrant in this example is potassium hydroxide, having a concentration of 0.121 M. The titrant is added to a buret. After slowly adding the titrant to the flask, the reaction…
