A buffer solution is prepared by adding NaC2H2O2 to a solution of HC2H2O2 (acetic acid).
HC2H3O2(aq) = H+ (aq) + C2H302 - (aq)
What happens if KCI is added?

Amount of liquid measured in l or lm

Ahypothrticalax type of ceramic material is known to have a density of 2.10 g/cm3 and a unit cell of cubic symmetry with a cell edge length of 0.57 nm. the atomic weights of the a and x elements are 28.5and 30.0 g/mol, respectively. on the basis of this information, which of the following crystal structures is (are) possible for this material: sodium chloride, cesium chloride, or zinc blende

Select all that apply. using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 (s) pb+2(aq) + 2cl -(aq). the concentration of the products yield a ksp of 2.1 x 10-2:
