Determine the OH− in a solution with a pH of 3.7.

Determine the concentrations of hydronium and hydroxide ions in 8.14 × 10−3 M aqueous perchloric acid. [OH−] = [H3O+]=

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 we write it as Ca(OH)2(s).Below is a list of the 6 strong acids and 6 strong bases you should know. All other acids and bases are considered weak. Strong Acids Strong Bases HCl, HBr, HI LiOH, NaOH, KOH HNO3 Ca(OH)2 (slightly soluble) HClO4 Ba(OH)2 H2SO4 Sr(OH)2 What is the hydronium ion concentration in an aqueous hydrochloric acid solution with a pH of 4.250?[H3O+] =  M
