The given ionic reaction has to be balanced and the
Concept Introduction:
An
Galvanic cell consists of two half-cells. The redox reaction occurs in these half-cells. The half-cell in which the reduction reaction occurs is known as the reduction half-cell, whereas the half-cell in which the oxidation reaction occurs is known as the oxidation half-cell.
The standard cell potential for voltaic cell is determined by subtracting the electrode potential of cathode and the electrode potential of cathode.
The negative cell potential of a redox reaction indicates that the reaction is not spontaneous which shows that the standard free energy should be less than 0. The reverse reaction of this will be definitely a spontaneous reaction with cell potential value greater than 0.
- Chemical equation is the representation of a
chemical reaction , in which the reactants and products of the reactions are represented left and right side of an arrow respectively by using their respective chemical formulas. - Reactant of a chemical reaction is the substrate compounds or the compounds which undergo a chemical reaction.
- Product of a chemical reaction is the produced compounds or the compounds formed after a chemical reaction.
- Balanced chemical equation of a reaction is written according to law of conservation of mass.
- Stoichiometry of a chemical reaction is the relation between reactants and products of the reaction and it is represented by the coefficients used for the reactants and products involved in the chemical equation.

CN + En CNarrow_forward3) Propagation of uncertainty. Every measurement has uncertainty. In this problem, we'll evaluate the uncertainty in every step of a titration of potassium hydrogen phthalate (a common acid used in titrations, abbreviated KHP, formula CsH5KO4) with NaOH of an unknown concentration. The calculation that ultimately needs to be carried out is: concentration NaOH 1000 x mass KHP × purity KHP molar mass KHP x volume NaOH Measurements: a) You use a balance to weigh 0.3992 g of KHP. The uncertainty is ±0.15 mg (0.00015 g). b) You use a buret to slowly add NaOH to the KHP until it reaches the endpoint. It takes 18.73 mL of NaOH. The uncertainty of the burst is 0.03 mL.. c) The manufacturer states the purity of KHP is 100%±0.05%. d) Even though we don't think much about them, molar masses have uncertainty as well. The uncertainty comes from the distribution of isotopes, rather than random measurement error. The uncertainty in the elements composing KHP are: a. Carbon: b. Hydrogen: ±0.0008…arrow_forward
