1.) Sample size is given as 10 grams - you need to measure weight since many of the materials contain solids as well as liquid.
2.) Identity and expected concentration of ingredient to analyze?
3.) Balanced chemical equation for titration?
4.) Moles of ingredient in 10 grams and moles of titrant that will react with this during titration.
5.) Molarity of titrant needed to require 25 mL of titrant?
6.) pKa for ingredient. Include all pKa if more that one. If more than one, arrange your titration to titrate all acids or bases.
7.) Indicator choice based on pKa above.
