Match each titration term with its definition. Solution of an unknown concentration that has another solution slowly added to it
When the required amount of one solution has been added to the second solution to complete the reaction
Solution of known concentration that is slowly added to a solution of unknown concentration
Glassware that allows a solution to be precisely and slowly added to another solution
A reagent added to the analyte solution that changes color when the reaction is complete
Process of slowly adding a solution to react with another solution and determine the concentration of one of the solutions based on the reaction between them

The answer to this is the 3rd choice!

    pb(so₄)₂this element is lead (iv) sulfate. lead is a multivalent ion. but we know that sulfate ions, so₄²⁻, have a charge of -2. in order to have the ratios match up, we need pb⁴⁺ (two times as many pb⁴⁺  than so₄²⁻).the molar mass can be calculated by finding the mass of one mole of this compound. consider the following calculation,  where amu represents the atomic mass unit. the amu for each atom involved in this compound can be found on a periodic table.  molar mass = amu pb + 2(amu s + 4 * amu o)from a periodic table (with masses rounded to the nearest tenth),      amu pb = 207.2 g    amu s =  32.1 g    amu o = 16.0 gtherefore    molar mass =  207.2 + 2(32.1 + 4*16.0) = 399.4 gthe molar mass is therefore 399.4 grams per mol
