Using the list of chemical species:
- C6H12O6
- CH3OH
- H2SO4
- H2C2O4
- HCN
- NH3
- NaOH
- Sr(OH)2
- CaCl2
- NaCl

Answer the questions:
1. Which species should have neutral pH? Explain why.
2. Conductivity is measured in siemens (S), and the typical unit measured for solutions is S/cm.The higher the value, the better the electrical conductivity. Which of the chemical species from the manifest would you expect to have the highest conductivities?
3. None of the samples are metallic, but we would like to use electrical conductivity as one of our tests. To do this we will prepare 0.10M solutions of each sample, based on its presumed identity. Which of the 0.10M species would you expect to conduct electricity well? Explain why
4. We will also measure the pH of the solutions. Which species should have low pH?

Also using the data below, and the chemical species listed above, what is the suggested identity of each sample (list from 1-10):
1_____ Conductivity (S/cm): 3.1 x 10-3, pH: 5.61, Characteristics: White crystalline solid
2____ Conductivity (S/cm):4.9 x 10-3 , pH:0.98, Characteristics: Dense, viscous liquid, turns paper black
3____ Conductivity (S/cm):3.8 x 10-6, pH:5.73, Characteristics: Flammable, low viscosity liquid
4____ Conductivity (S/cm):2.9 x 10-3, pH:13.21, Characteristics: White crystalline solid, solution is slippery on skin
5____ Conductivity (S/cm):4.7 x 10-3, pH:5.62, Characteristics: White crystalline solid
6_____ Conductivity (S/cm):4.6 x 10-4, pH:8.27, Characteristics: Sharp odour, white crystalline solid
7_____ Conductivity (S/cm):7.6 x 10-4, pH:2.91, Characteristics: Flammable, white crystalline solid
8_____ Conductivity (S/cm):4.3 x 10-5, pH:5.70, Characteristics: Flammable, white powdery solid
9_____ Conductivity (S/cm):3.8 x 10-4, pH:4.06, Characteristics: Flammable, low viscosity liquid
10_____ Conductivity (S/cm):5.2 x 10-3, pH:13.48, Characteristics: White crystalline solid, solution is slippery on skin
