Answer 2

Which of the following is not operational error?

Explanation:

• In this question, their are given four options and we have to find which one is not an operational error.
• (a) Compound is not dissolve completely in solvent: This option is describing that the solute (compound) which is added in the solvent has not completely dissolved which means it is an operational error.
• (b) Unable to predict colour change of indicator: This option states that the result has not been predicted well as the change in colour of an indicator could not be specifically predicted by an observer. Hence this is not the operational error. It is the observational error.
• (c) Solution are not transferred properly: This option states that the transfer of solution is not done properly which is again a type of operational error.
• (d) Incomplete drying of sample​: This option states that the sample which have been taken is not dried properly and this is again a type of operational error.
• Hence, it can be concluded that the correct answer of this question is (b) Unable to predict colour change of indicator which is not the type of operational error.
