Chapter 3, Problem 3.11P

Interpretation Introduction

Interpretation:

Whether the apparent mass of the product of gravimetric analysis under the given condition is always high or always low has to be explained; also state whether the error in mass is systematic or random.

Concept Introduction:

Systematic error:

These error occur due to instrumental flaws or due to errors in experimental design. These errors can be replicated. It can be detected and corrected. These errors are otherwise called as determinate errors.

Random error:

Random errors are uncontrollable, unpredictable and are completely random. These errors are not reproducible. These are caused due to instrumental changes or due to the change in the measuring environment. Random errors has an equal chance of being positive and negative. These errors are otherwise called as indeterminate errors.
