Question

A metal (X) dissolves both in dilute HCl and dilute NaOH to liberate H ₂ . Addition of NH ₄ Cl and excess NH ₄ OH to an HCl solution of X produce Y as a precipitate. Y is also produced by adding NH ₄ Cl to t he NaOH solution of X . The species X and Y , respectively, are

Quantrex Academy · Accepted Answer

Correct answer: B. Al and Al (OH) ₃

array ll Zn + NaOH Na ₂ ZnO ₂ & Al + NaOH NaClO ₂ Zn + HCl ZnCl ₂+ H ₂ & Al + HCl AlCl ₃+ H ₂ array ZnCl ₂ gives no ppt with NH ₄ Cl + NH ₄ OH solution. But AlCl ₃ gives gelatinious white ppt of Al ( OH )₃ with NH ₄ Cl + NH ₄ OH .
