Question

e Shenon at is the difference between hydrogen chloride and hydrochloric acid? Hydrogen chloride is a gas while hydrochloric acid is aqueous 3. Calcul Calculate the molarity (moles of tert-butyl chloride per liter of solution) of the tert-butyl chloride in acetone given at the end of this week's lab procedure. Show your work. The density of tert-butyl chloride at room temperature is 0.842 g/mL). - = 0.00492 L ) 0.842 100ML 9.1439 x ImL * IL 0.842 M = o.ous moles 0.00492 4. Upon addition of water, the tert-butyl chloride will undergo hydrolysis within a matter of minutes to form tert-butyl alcohol plus HCI. That is: tert-butyl chloride + H2O → tert-butyl alcohol + HCI (a) If 5.0 mL of your acetone solution of tert-butyl chloride undergo hydrolysis completely, how many moles of HCI will be produced? (b) Calculate the pH of the solution from 3(a). Remember that pH = -log (H301" and that [H3O]* = moles HCI/ml solution.

Answer 1

U fed-butyl chloride + H20 let - budyl alcohol + HC volume of t-butyl chloride solution = 5ml density off to t-butyl chloride = 0.842 gmb-l. : Mass of t- butyl chloride - 506 x 0.842gme? present initally (re, before reaction) = 4.219 Moles ok t-butyl chloruiden- 4.215. 92.57 gmolet = 0.0455 mole Since of I mole of Ha after t-butyl chloride gives complete hydrolysis . i mole - 0.0455 male t-butyl chloride gives 0.0455 mole of HU Thus, no of mole of HU = 0.0455 mole [H30] = moles of HU volume of solution 0-0455 mol *1000/? = gol mole Lt . ..pH = -log HOT J = -0.96 A .
