What is the balanced equation for lead with hydrochloric acid?
WebLead (IV) oxide reacts with concentrated hydrochloric acid as follows: PbO2 (s) + 4HCl (aq) -----> PbCl2 (s) + Cl2 (g) + 2H2O (l) What mass of lead chloride would be obtained from 37.2g of PbO2, and what mass of chlorine gas would be produced In this question we have to use the equation Moles= Mass (g)/ Mr. WebLead reacts slowly with hydrochloric acid and nitric acid, HNO 3. In the latter case, nitrogen oxides are formed together with lead (II) nitrate, Pb (NO 3) 2. Reaction of lead with bases Lead dissolves slowly in cold alkalis to form plumbites. WebMar 27, 2016 · Both of these oxides will react with concentrated hydrochloric acid to produce aqueous lead (II) chloride, PbCl2, and water. However, the difference between the two lead oxides is that lead (IV) oxide will also oxidize hydrochloric acid to chlorine gas, Cl2. You can thus say that 2+2 PbO(s] +4H−1 Cl(aq] → 2+2 Pb−1 Cl2 (aq] +2H2O(l] greens bayou corridor coalition
