Which equation represents a neutralization reaction? 1) CaO-H05Ca(OH)2
2) 2 HCI - Zn → ZnCl2 + H2
3) H. SO. - Caco, → Caso, -H,0-CO,
4) HNO, - KOH → KNO; -H,0

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:
