1) A strong acid is the acid that is 100% dissociated in aqueous media----TRUE
a strong acid may have 100% or slightly less than 100% dissociation because those molecule are acidic which give H+ ion on dissociation if the molecule did not dissociate it will did not provide H+ so not strong acid.
2) Using gravimetry to quantify silver content based on insoluble AgX (X=Cl, Br,or I), we prefer AgCl----FALSE
Silver nitrate is used to precipitate chloride because it gives the best results
3) The analyte is usually placed in the Erlenmeyer flask, which is called a direct titration. By swapping reagnt buret with analyte in the Erlenmeyer flask, we call the new setup as a back titration -----FALSE
A back titration is a titration method where the concentration of an analyte is determined by reacting it with a known amount of excess reagent whereas a direct titration directly measures the concentration of the unknown compound. ... A back titration may also be called an indirect titration,
