WebThe surface of metallic lead is protected by a thin layer of lead oxide, PbO. This renders the lead essentially insoluble in sulphuric acid, and so, in the past lead was a useful container … WebPart III. Based on the observations in Table 8, we can determine some information about the relative activity of metal M. Metal M is less reactive than lead (Pb) since it displaces lead from Pb(NO 3) 2 solution and forms a dark gray precipitate on the surface of M.; Metal M is less reactive than silver (Ag) since it displaces silver from AgNO 3 solution and forms a …

Web2 years ago. Undiluted acids are very dangerous. Concentrated HCl or Concentrated H2SO4 will react VERY vigorously with the metal. The reaction with concentrated acids is highly exothermic (releasing heat). The H2 gas that is produced as a result of the reaction might get ignited by the heat, and burn violently. WebMar 24, 2024 · Balance the equation with one mole of lead nitrate, or Pb (NO3)2, with two moles of hydrochloric acid, or HCl, to produce one mole of lead chloride, or PbCl2, with two moles of nitric acid, or HNO3. This entire reaction takes place in an aqueous solution of water. Break down the equation into all its parts WebMay 10, 2024 · The reaction taking place is reversible. [ Co ( H 2 O) 6] 2 + + 4 Cl − ↽ − − ⇀ [ CoCl 4] 2 − + 6 H 2 O Concentrated hydrochloric acid is used as the source of chloride ions because it provides a very high concentration compared to what is possible with, say, sodium chloride solution. how do you pierce your own ears
