Which of the following salts is the most acidicin aqueous solutions?1. Pb(NO3)22. Fe(NO3)23. BaCl24. AgNO35. Al(NO3)36. KBr7. NaIA 0.456 gram sample of an unknown monoprotic acid (let’s call it HZ) was dissolved insome water (you pick the amount). Then theacidic solution was titrated to the equivalencepoint with 32.5 mL of 0.174 M KOH. Whatis the molecular weight of the unknown acidHZ?1. 85.7 g/mol2. 103.2 g/mol3. 80.6 g/mol4. 0.00259 g/mol5. 187.9 g/moA 1.996 gram sample of unknown monoproticacid is dissolved in some water. This acidsolution is then titrated to the end point with27.38 mL of a solution of 0.4165 M KOH.What is the molar mass of the unknown acid?1. 54.7 g/mol2. 128. g/mol3. 94.3 g/mol4. 4.79 g/mol5. 175. g/moIn neutralization reactions,acid + base → salt + waterHCl can be neutralized with NaOH. Howmany moles of NaOH will it take to neutralize0.65 L of 0.34 M HCl?Answer in units of mol.A 32 mL sample of a solution of sulfuric acidis neutralized by 28 mL of a 0.163 M sodiumhydroxide solution. Calculate the molarity ofthe sulfuric acid solution.Answer in units of mol/L.011 10.0 pointsIf 300 mL of 2.3 molar HCl solution is addedto 300 mL of 4.8 molar NaOH solution, whatwill be the molarity of NaCl in the resultingsolution?Answer in units of M.012 10.0 pointsIf 393 mL of 3.5 molar HCl solution is added to127 mL of 2.9 molar Ba(OH)2 solution, whatwill be the molarity of BaCl2 in the resultingsolution?Answer in units of M.
