    Error Sampling
AI Thread Summary
Using a homogeneous mixture in experiments ensures consistent composition throughout the sample, which is crucial for accurate and reliable results. In contrast, heterogeneous mixtures can lead to variability in component ratios, causing random fluctuations that affect the outcome of the experiment. This inconsistency can result in difficulties in replicating results and interpreting data, as different samples may yield different outcomes. The discussion emphasizes the importance of uniformity in experimental mixtures to maintain the integrity of scientific findings.

Why do you have to use a homogenous mixture in an experiment what are the disadvantages of using a heterogenous mixture?
 
Chemistry news on Phys.org
Mixture of what, in which experiment?

My guess: If you use some specific amount of a heterogenous mixture, the ratio of the components inside (in that specific amount) might differ due to random fluctuations.
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
