List the species present in an aqueous solution of each of the following: a. HF b. KOH c. NH3 d. HCl e. Ba(OH)2 Given the concentrations of the following solutions provide the pH, pOH, H3O, and OH- a. 0.0025 M HCl b. 0.0025 M NaOH c. 0.035 M Ba(OH)2 d. 0.0015 M H2SO4
what
is solution ?
(References) Strong acids and strong bases ionize 100% in aqueous solution - HCl is a strong acid. In solution we write it as H(aq) + Cl(aq). - HF is a weak acid. In solution we write it as HF (aq). - KOH is a strong base. In solution we write it as K (aq) + OH(aq). - NH3 is a weak base. In solution we write it as NH3(aq). Exception: Since Ca(OH)2 is only slightly soluble...
