NaOH is strong base, HCl a strong acid, solution is neutral NH4Cl + HOH ==> NH4OH + HCl NH4OH (NH3 + HOH) is a weak base, HCl a strong acid, solution is acidic. This compound in an aqueous solution will, therefore, form a basic . Neutralization of any strong acid with a strong base always gives a neutral salt. First statement is correct. Water accepts a proton from vinegar. And we have the K A values and K A B values and tables 14.2 and 14.3. H 3 O +. Hu Hot Menu, CH3NH3Cl is an ionic compound, consisting of CH3NH3+ and Cl- ions. So the salt contains an ionic part which is base of a weak acid. Identify the nature of the salts in an aqueous solution. No packages or subscriptions, pay only for the time you need. Assume 2 significant figures in all of the given concentrations so that you should calculate all of the following pH values to two decimal places. CH3NH3CN - basic g. NaNO2 - basic h. KOCl - basic 5. One difficult aspect of acid-base chemistry is recognizing what types of species are present in solution, i.e., whether a species is a strong acid, strong base, weak acid, weak base or a neutral species. Will an aqueous solution of CH3NH3CN be acidic, basic or The equation for CH3COONa is:CH3COOH + NaOH = CH3COONa + H2OIt is also useful to have memorized the common strong acids and bases to determine whether CH3COONa acts as an acid or base in water (or if it forms a neutral solution).Strong acids: HCl, H2SO4, HNO3, HBr, HI, HClO4Weak acids: HF, CH3COOH, H2CO3, H3PO4, HNO2, H2SO3Strong Bases: LiOH, NaOH, KOH, Ca(OH)2, Sr(OH)2, Ba(OH)2Weak Bases: NH3, NH4OHNote that we are talking about whether CH3COONa is an acid, base, or neutral when dissolved in water.- Salts of strong bases and strong acids: pH will remain neutral at 7.- Salts of weak bases and strong acids: pH less than 7 (acidic).- Salts from strong bases and weak acids: pH greater than 7 (alkaline).Based on these rules, the solution of CH3COONa dissolved in water is basic.For polyprotic acids (e.g.
