Question
1. Carbon Dioxide gas bubbles from a reaction mixture of an acidand carbonate ion. Write the net ionic equation showing thereaction.2. Sulfite salts have properties similar to those of carbonatesalts. Predict the reaction, using a net ionic equation of sulfitesalts with acid.
3. Ammonia is always evolved when ammonia salt is place between abasic solution.. Write the net ionic equation showing thereaction.
Explanation / Answer
1. Lets take Na2CO3 +2HCl --> 2NaCl+H2O +CO2 now lets take the reaction and split it into ions.. 2Na+ + CO32-+2H+ + 2Cl- -->2Na+ + 2Cl-+ H2O + CO2 --cancel the commonions...(H2O and CO2 are covalent and do notdissociate) gives us: CO32- +2H+ --> H2O +CO2 (acid and carbonateion give water and carbon-dioxide) 2. This is almost the same as carbonates.. Lets take similar saltsto make things easier.. Na2SO3 +2HCl --> 2NaCl +H2O+SO2 Follow the same steps as above and you get: SO32- +2H+ -->H2O + SO2 3.NH4Cl +NaOH --> NaCl +H2O +NH3 (note: ammonia and water are covalent and won'tdissociate) ionic equations for the reaction: NH4+ +Cl-+Na+ +OH- -->Na+ +Cl-+H2O +NH3 --cancel out the common ions... we get: NH4+ +OH- -->H2O +NH3 (ammonium ions in abasic[OH-] medium liberated water and ammonia) done !!
