vii. Explain the distinctly different behavior in the conductivity of NaCl(s) and NaCl(aq). What species are present in each of these substances? Species Present NaClaq) NaCl(s) vii. What species are present in 0.1 M HCl and NaOH solutions? Write equations to describe the reactions that yield these species. Species Present Equation HCl(aq) NaOH(aq) B. The effect of the solvent Why is the conductivity of HCI (or CH,COOH) different in the two solvents? What causes this difference Correlating chemical and conductivity behavior i. Compare the rates of reaction of CaCO, (s) with 6 M acetic acid and 6 M hydrochloric C. acid. The reaction of CaCO, with an acid, HA, is 2 HA(aq) + CaCO3(s) Ca2+ (aq) + 2 Afaq) + CO2(g) + H20) Compare the rates of reaction of Zn(s) with 6 M CH,COOH and 6 M HCI. The reaction of zinc with an acid, HA, is ii. 2 HA(aq) + Zn(s) Zn2+ (aq) + 2 A-(aq) + H2(g) Experiment 10: lonic and Covalent Bonding-Report 119

Explanation / Answer

Ans. NaCl(s) is in solid state and it can not conduct electricity because for conducting there is must charge species where as NaCl(aq) is in aqueous solution and it dissociates into Na+ and Cl- and these two ions are responsible for conducting in nature.

Ans. HCl(aq) + NaOH(aq) = NaCl(aq) + H2O(aq)
