Question- A substance, C, decomposed by water is initially dissolved in water (at t=0) to form a 1.0M solution. At the end of 100,000 s, 50% of C remains unreacted. What percentage of C will remain at t=1week if the reaction is second order in C only to 3 significant figures?
Does this question make sense? Why or why not?
I just need a general explanation of it please- Thanks!
At pH 12, magnesium hydroxide is insoluble and does not react with EDTA. The titration of a hard water sample at pH 12 thus yields results for calcium only. A 250.0-mL sample of tap water was adjusted to pH 12 and titrated with 0.01056 EDTA using ..
