Question

Please complete the Data sheet ( just doing the first column with explanation, would be enough) Thank you Data Sheet solution number volume of 0.10M NaCl used, mL olume of 0.10M KCI used, mL NaCI] KCl] emperature of filtered KHT solution, C 1M y of standardized NaOH solution, mol L-1 OBBM determination volume of saturated KHT solution titrated, mL NaOH solution final buret reading, mL initial buret reading, ml volume of NaOH needed, mL number of moles of NaOH needed, mol number of moles of HT titrated, mol HT 1st so solubility of KHT/mol L-1. K lnitial K rom dssolved KHT average Ksp average solubility of KHT, mol L- average solubility, grams per 100 ml

Explanation / Answer

moles of HT- titrated --> must be equal to those of NaOH, since ratio is 1:1

so

moles of HT- = 4.88*10^-4 mol

so..

[HT-]sat. soln = mol/V = (4.88*10^-4) / (35 mL) = (4.88*10^-4)/(35*10^-3) = 0.013942 M

solubility must be then --> 1:1 raito -- >0.013942 M of KHT

so..

[K+]initially = 0.1

[K+] = 0.013942

[K+] sat = 0.1+0.013942 = 0.113942

Ksp = [K+][HL-T] = 0.113942 * 0.013942 = 0.001588579
