Question

write the equation of reaction of sodium bicarbonate with water​

Answer 1

Explanation:

$The molecular equation for the chemical change is:</p><p>NaHCO3+H2SO4→Na2SO4+H2O+CO2</p><p>NaHCO3,H2SO4 and Na2SO4 are ionic compounds; so these are written in ionic forms.</p><p>Na++HCO3−+2H++SO42−→2Na++SO42−+H2O+CO2</p><p>Na+ and SO42− ions are spectator ions; hence these shall not appear in the final equation.</p><p>HCO3−+2H+→H2O+CO2</p><p>To make equal charges on both sides, HCO3− should have a coefficient 2.</p><p>2HCO3−+2H+→H2O+CO2</p><p>In order to balance the hydrogen and carbon on both sides, the molecules of H2O and CO2 should have a coefficient 2 respectively.</p><p>2HCO3−+2H+=2H2O+2CO2</p><p>or HCO3−+H+=H2O+CO2</p><p>This is the balanced ionic equation.</p><p></p><p>$
