Ex2: A 0.2025 g sample consisting of only BaCl2 and KCl required 20.25 mL of 0.1200 M AgNO3 solution for the quantitative precipitation of chloride. Calculate the %Ba and %K in the sample.

Why is it important for scientists to replicate each other’s experiments? to determine if important scientific results are repeatable to the research of other scientists to determine if slight alterations in the experiment can affect the result to further their own research
