A secоnd grоup cоllects different results.SаmpleBuffer levelDrops of NаOH needed to reаch pH ≥ 7Sample 1Low buffer8Sample 2Medium buffer31Sample 3High buffer15The group concludes that medium buffer has the greatest buffer capacity.Do you agree with their conclusion? Explain your answer using the expected relationship between buffer concentration and NaOH drops. Identify one possible experimental mistake that could explain the unexpected pattern.
