Unformatted text preview: d. After drying the crucible, it should be taken out and put in a desicooler to cool. Once cool, the weight and mass of BaSO+ should be determined, thus calculating the original concentration of the Ba(OH)2 solution. .\, t ' Cond ucti metric Titration i Linear Fit For: Latest:Conductivity j y=mx+b i m(Sfope): -1 268 pS/cm/mL b(Y-lntercept): 1,928E+004 pS/cm l Conelation:-0.9911 ll--;t I I Volume:0.50 mL I j Conductivity: 17633.3 pS/cm ' Equivalence Point from Titration (mL) Molarity of Hz SO+ solution Moles of barium from Titration (mol) Volume of original Ba(OH)2 soln (mL) Conc.
