Magnesium is produced commercially by electrolysis from a molten salt using a cell similar to the one shown here.
(a) What salt is used as the electrolyte?
(b)Which electrode is the anode, and which one is the cathode?
(c)Write the overall cell reaction and individual half-reactions.
(d) What precautions would need to be taken with respect to the magnesium formed?
1) The standard potential of the cell Ag(s)|AgCl(s)\\Cl-(aq)||Ag (aq)|Ag(s) is 0.58 V at 25 °C. Calculate the equilibrium constant for the cell reaction.
For each reaction, calculate the mass (in grams) of the product formed when 10.1g of the underlined reactant completely reacts. Assume that there is more than enough of the other reactant.
Write the cell notation for the voltaic cell that incorporates eachof the following redox reactions.
What is the pH at the half-stoichiometric point (that is, what is the pH when you have added 50% of the total volume of base required to react with all of the acid originally present?)
The true rate constant for a reaction is just that, a constant( at the constant temperature). Would your calculated value for k be higher than, lower than, or equal to the real value of k if 5 wt% bleach was unknowingly substituted with 8wt% bleac..
A 0.879-g sample of a CaCl2*2H20/K2C2O4*H20 solid salt mixture is dissolved in-150mL of deionized water, previously adjusted to a pH that is basic. The precipitate, after having been filtered and air-dried, has a mass of 0.284 g.
