Deviation in a particular measurement is the difference between the measured value and the average value The arithmetic mean of the different deviations observed in several measurements of the same quantity is known as.
It has been observed that if one goes on adding KNO3 solution to a precipitate of AgCl the solubility of these precipitates goes on increasing with increasing concentration of K+ and NO3= ions which are not common to AgCl This is due to which effect.
When to a solution of weak electrolyte a strong electrolyte with a common ion is added, the dissociation of weak electrolytes is suppressed . This is known as.
