Neutralization reactions and salts

(c) After 30 minutes, the student stopped heating the mixture and titrated a sample of the solution remaining in the flask with NaOH to determine the experimental yield of propanoic acid. Explain why the titrated sample will give an incorrect value for the…

Nitrogen dioxide reacts with rain water and oxygen to form nitric acid. (i) State an equation for this reaction, including state symbols. (ii) Explain, with reference to the oxidation states of two elements, why this is a redox reaction. (iii) Describe the…

Which equation correctly represents a reaction of dilute sulfuric acid? A. $\ce{H2SO4 + MgCO3 -> MgSO4 + CO2 + H2O}$ B. $\ce{H2SO4 + 2Ag -> Ag2SO4 + H2}$ C. $\ce{H2SO4 + 2KOH -> K2SO4 + H2}$ D. $\ce{H2SO4 + 2NaHCO3 -> Na2SO4 + 2H2O}$

(i) In aqueous solution sulfuric acid transfers a proton to a water molecule, forming the hydroxonium ion, $\ce{H3O+}$. Annotate the structure of the hydroxonium ion to indicate the coordination bond. (ii) Write an equation for the reaction between excess…

When sodium hydroxide solution is added to the water, a larger amount of bromine reacts. Explain this observation.

Which reactions involve the transfer of a proton? I. $\ce{H2SO4(aq) + Zn(OH)2(s) -> ZnSO4(aq) + 2H2O(l)}$ II. $\ce{H2SO4(aq) + ZnCO3(s) -> ZnSO4(aq) + H2O(l) + CO2(g)}$ III. $\ce{H2SO4(aq) + Zn(s) -> ZnSO4(aq) + H2(g)}$ A. I and II only B. I and III only C. II…
