Precipitation reaction and double displacement reaction
The rate of a reaction refers to the speed at which the reaction takes place. The rate of a reaction depends on many variables such as, temperature, concentration of dissolved reactants, pressure of gaseous reactants, surface area of solid reactants, or the presence of a catalyst. In order to measure the rate of a reaction, we must measure the change in amount of a reactant as it is consumed over time, or measure the amount of product formed over time. When you graph the formation of a product, or consumption of a reactant on the y axis, versus the time of reaction on the x-axis, the slope of this function will provide the rate of the reaction.
<span>Copper sulfate, CuSO4 ===> (Cu^2+) (SO4^2-). </span>
<span>That means copper ions have a positive charge in the solution of this compound and are therefore attracted to the negative electrode, cathode. Just wanted to clear that out because "it accepts electrons there" is an invalid and ambiguous answer. </span>
<span>Good luck.</span>
Answer:
Heating is the best method
Explanation:
When a mass of crystals containing Water of crystallization is heated sufiiciently to a high temperature, water vapor may be driven off the crystals by the action of heat alone.
