Write titration of unknown iron sample with permanganate – KMnO4
Fe2+ → 5Fe3+ + e–
MnO4– + 8H+ +5e– → Mn2+ + 4H2O
MnO4– (aq) + 8H+ (aq)+5Fe2+ (aq) → Mn2+ (aq) + 4H2O (l) + 5Fe3+ (aq)
Use the balanced equation and average titration volume of the titration of the unknown sample to find the mass of iron in the sample (Fe 55.85 g/mol and % of iron in the unknown sample
Average titration volume: 2,55 mL

As such, it is important for the management to come up with strategies to change job satisfaction into positive employee behavior. To begin with, the manager must come up with means of rewarding employees who register exemplary performance. This will increase the employee satisfaction levels of such employees as they feel that their hard work is being appreciated by the organization.
The manager should also involve employees in decision making especially on matters that directly affect them (Robbins & Judge, 2011). This will make employees feel like being part of the organization thus boosting their morale. Further, managers need to come up with occasional surveys to determine employee satisfaction levels. This will enable the management ascertain areas, which they need to improve in order to satisfy their employees.
In particular, if I was in the position of a manager, I will begin by undertaking employee satisfaction survey in order to ascertain areas of dissatisfaction. Thereafter, I will implement the recommendations thereof in order to improve employee job satisfaction levels. Once implemented, I will undertake an employee satisfaction exit survey. The exit survey will help in evaluating the success of the strategies employed with the aim of boosting employee job satisfaction
