You need the data from the lab in section 1; Using pH to identify acids, bases and salts.
1. Create a spreadsheet that has the following columns and enter the formulas for the solutions you used in section 1. See example below. (We are using the spreadsheet because the one we have access to does not allow subscripts and we are typing chemical formulas.)
| formula | classification | Cation | charge | m/nm | anion | charge | m/nm | # of elements | # of atoms | binary/ ternary |
| KCl | ||||||||||
| KOH | ||||||||||
| NaCl | ||||||||||
| HCl | ||||||||||
| H2SO4 | ||||||||||
| CuSO4 | ||||||||||
| NaOH | ||||||||||
| HNO3 | ||||||||||
| NH4OH |
Once you have your spreadsheet designed enter the correct data into each column. If you aren’t sure what information belongs in the cells, look below for a description of the information that belongs in the cells.
Formula = chemical formula of compound.
Classification = acid, base, salt. Later as your spreadsheet grows you will add the classifications of metal and nonmetal oxides.
Cation = symbol for the element that acts as the positive ion.
Charge = charge of cation. The oxidation or valence # belongs here.
M/NM = identify the cation as a metal or nonmetal. (Metals are to the left of the stairstep line on the periodic chart and nonmetals are on the right.)
Anion = symbol for the element that acts as the negative ion.
Charge = charge of anion. The oxidation or valence # belongs here.
N/NM = identify the anion as a metal or nonmetal.
# of elements = count the # of elements in the compound.
# of atoms = count the # of atoms in the compound.
Binary/ternary = identify each compound as a binary or ternary. You should leave this blank until question number 4.
