Would you expect the heterogeneous method to give a higher percent nickel or a lower percent nickel than the homogenous method? Explain your answer. (From the Quantitative Determination of Nickel in a Compound By Gravimetric Analysis lab)

Heterogeneous method

Explanation:

In general, a gravimetric method of analysis consists

of the following steps:

Weighing and dissolving the sample in the proper solvent.

Carrying out a sequence chemical reactions to  obtain a suitable product.

Determining the mass of the product

Calculating the composition of the sample rom mass of product and information about the original sample.

Precipitates obtained by heterogeneous methods are often difficult to filter and are always contaminated by  adsorbed and occluded impurities which ultimately increase the percentage yield of  nickel due to occluded impurities.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
