Salts of Weak Acids. Need help with this topic in General Chemistry. Thank you in advance ! :)
30. Predict which is the strongest acid? (a) CHs (b) NH (c)HO (d) HF 25. Determine if each salt will form a solution that is acidic, basic, or pH neutral. (a) SrClz (f) Ca(NOs)2 (b) NaCHO (g) NacIo (c) AIBra (d) NHaF (e) CH3NH3NO3 Kb (NH3)= 1.76x 105 k, (HF) = 3.5 x 104 Other problems: 24 Salts of Weak Acids 4. Calculate the pH of a 0.100 M sodium formate (NaCHO2) solution. The K of HCHO2 is 1.8 x 104 15. Sodium fluoride (NaF) is a source of fluoride in some toothpastes. Determine the [H'] at equilibrium, and the pH of a 0.22 M NaF solution at 25 *C. The Ka of HF is 3.5 x104.
