With very dilute H N O3, Zn produces N2O.

Q. In which of the following reactions, the product(s) given is/are not correct?

$3 C u + 8 H N O_{3} ($ dil. . $\to 3 C u (N O_{3})_{2} + 2 NO + 4 H_{2} O$

$3 Z n + 8 H N O_{3} ($ very dil. $) \to 3 Z n (N O_{3})_{2} + 2 NO + 4 H_{2} O$

$4 S n + 10 H N O_{3} ($ dil. $.) \to 4 S n (N O_{3})_{2} + N H_{4} N O_{3} + 3 H_{2} O$

As $+ 3 H N O_{3} ($ dil. $.) \to H_{3} A s O_{3} + 3 N O_{2}$

With very dilute $H N O_{3}, Z n$ produces $N_{2} O .$

Q. In which of the following reactions, the product(s) given is/are not correct?

3Cu+8HNO3​( dil. . →3Cu(NO3​)2​+2NO+4H2​O

3Zn+8HNO3​( very dil. )→3Zn(NO3​)2​+2NO+4H2​O

4Sn+10HNO3​( dil. .)→4Sn(NO3​)2​+NH4​NO3​+3H2​O

As +3HNO3​( dil. .)→H3​AsO3​+3NO2​

With very dilute HNO3​,Zn produces N2​O.

$3 C u + 8 H N O_{3} ($ dil. . $\to 3 C u (N O_{3})_{2} + 2 NO + 4 H_{2} O$

$3 Z n + 8 H N O_{3} ($ very dil. $) \to 3 Z n (N O_{3})_{2} + 2 NO + 4 H_{2} O$

$4 S n + 10 H N O_{3} ($ dil. $.) \to 4 S n (N O_{3})_{2} + N H_{4} N O_{3} + 3 H_{2} O$

As $+ 3 H N O_{3} ($ dil. $.) \to H_{3} A s O_{3} + 3 N O_{2}$

With very dilute $H N O_{3}, Z n$ produces $N_{2} O .$
