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.
The concentration of the HCl solution is 0.1016 M HCl. What volume of 0.1338 M Ba(OH)2 would neutralize 50.00 mL of the HCl solution standardized in the situation above.
The mass ratio of sodium to fluorine in sodium fluoride is 1.21:1. A sample of sodium fluoride produced 36.5 {rm g} of sodium upon decomposition. How much fluorine (in grams) was formed?
What is the value of the equilibrium constant for the neutralization of acetic acid with sodium hydroxide? The Ka for acetic acid is 1.8 ? 10-5 and the neutralization reaction of interest is CH3CO2H(aq) + NaOH(aq) -> H2O(l) + NaCH3CO2(aq).
If 158 mL of wet H2 is collected over water at 24C and a barometric pressure of 737 torr, how many grams of Zn have been consumed?
