nces to What is the name of the compound with the formula KCN? What is the...
answer all please!! thanks!! Give the name of the molecular compound and the name of the aqueous solution for each of the binary compounds below. Molecular Name Acid Name Formula HCN HF H S Are these species strong acids or weak acids in aqueous solution?
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...
Consider the following data on some weak acids and weak bases acid base name formula name formula hydrocyanic acid HCN 4.9 x 10 10 NH31.8 x 10 ammonia hypochlorous acid HCIO 3.0x 10pyridine CHN 1.7x109 Use this data to rank the following solutions in order of increasing pH. In other words, select a the solution that will have the next lowest pH, and so on next to the solution that will have the lowest pH, a '2' next to solution...
