Question 16

Which reaction is a redox reaction?

KOH+HNO3→KNO3+H2O\text{KOH} + \text{HNO}_3 \rightarrow \text{KNO}_3 + \text{H}_2\text{O}KOH+HNO3​→KNO3​+H2​O

BaCl2+Na2SO4→BaSO4+2NaCl\text{BaCl}_2 + \text{Na}_2\text{SO}_4 \rightarrow \text{BaSO}_4 + 2\text{NaCl}BaCl2​+Na2​SO4​→BaSO4​+2NaCl

CaCO3+2HCl→CaCl2+H2O+CO2\text{CaCO}_3 + 2\text{HCl} \rightarrow \text{CaCl}_2 + \text{H}_2\text{O} + \text{CO}_2CaCO3​+2HCl→CaCl2​+H2​O+CO2​

MnO2+4HCl→MnCl2+2H2O+Cl2\text{MnO}_2 + 4\text{HCl} \rightarrow \text{MnCl}_2 + 2\text{H}_2\text{O} + \text{Cl}_2MnO2​+4HCl→MnCl2​+2H2​O+Cl2​
