A reaction inside a cylindrical container with a movable piston causes the volume to change from 14.0L to 21.0L while the pressure outside the container remains constant at 0.975 atm. (The volume of a cylinder is V=??r2?h, where h is the height; 1 L×atm=101.325J) The diameter of the piston is 15.0
Which metal hydroxide will precipate first? Why? Ksp Ni(OH)2 = 6.0x10-16 Ksp Ce(OH)3 = 6.0x10-22 Ksp Cu(OH)2 = 4.8x10-20
Furthermore, you conducted the experiment using Styrofoam coffee cups because of their effective insulation capabilities. Therefore, you were able to accurately measure the molar enthalpy change of the acid-base reaction.
