HF is a weak acid and NH3 is a weak base. Which of the following shows the correct order of increasing pH for solutions of the indicated salts? O NH4CI < NaCI < NaF O NaF < NH4CI < NaCl O NaCl < NaF < NH4CI NaCl < NH4CI < NF O NaF < NaCI < NH4CI

Classify the following salts as acidic/basic/pH neutral and write a hydrolysis equation for them where appropriate.    salt Acidic/basic/neutral Hydrolysis equation if applicable NaNO3         CsF         NH4Cl         KCl         Ba(CH3COO)2         CH3NH3I

Acids and Bases Predicting the qualitative acid-base properties of salts Consider the following data on some weak acids and weak bases: name acid hydrocyanic acid HCN hydrofluoric acid solution 0.1 M C-H5NHBr 0.1 M NaF 0.1 M KCN formula 0.1 M C6H5NH3Cl Explanation HF Use this data to rank the following solutions in order of increasing pH. In other words, select a '1' next to the solution that will have the lowest pH, a '2' next to the solution that will have the next lowest pH, and so on. Check Ka 4.9 × 10-10 6.8 x 10 X pH choose one choose one v choose one ✓ choose one ✓ base 3 K₂ name formula -10 aniline C6H5NH₂ 4.3 x 107 -9 pyridine C,H-N 1.7×10 ⁹

If one mole of each of the following are dissolved in one liter of water which solution would have the highest pH? NaCl Ca(OH)2 HC2H3O2 HCl
