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...

ACIDS AND BASES Calculating the pH of a weak base titrated with a strong An analytical Chemist is titrating 140.7 mL of a 0.6100 M solution of diethylamine (CH), NH with a 0.1700 M solution of HNO. The pk, of diethylamine is 2.89. Calculate the pH of the base solution after the chemist has added 180.5 ml of the HNO, solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution...

Lab 5 Buffers 1. Dissolved ions in salt solutions can act as acids or bases and react with water to produce hydronium ions or hydroxide ions that contribute to the pH of the salt solution. Since strong acids and strong bases completely ionize in solution, the reverse reaction essentially does not occur, meaning that the resulting conjugate base of a strong acid or conjugate acid of a strong base do NOT act as acids or bases. Ions that are conjugate...

Strong Acids and [H'] (and pH) The pH of a strong acid is the concentration of the strong acid. 1.OM HCI makes 1.OM H. Except H2SO4. Its pH is a little lower than that because: H2SO4(aq) H+ (aq) + HS07 (aq) Strong acids generally have K.>>1. We assume K = . The HSO, is a weak acid: HSO2 (aq) + H+ (aq) + S0 - Ka = 1.2 * 10-2 Weak Acids and [H+] (and pH) These are weak electrolytes....
