Question

Part I: pH
Use a pH meter to measure the pH values of 0.10 M solutions of thefollowing
compounds. Also put a drop or two of universal indicator in eachsolution. Record the
pH and the color of each solution.
Sodium chloride, NaCl Sodium hydrogen sulfate, NaHSO4
pH: pH:
Color: Color:
Sodium acetate, CH3COONa Acetic acid, CH3COOH
pH: pH:
Color: Color:
3
Sodium carbonate, Na2CO3 Sodium hydrogen carbonate, NaHCO3
pH: pH:
Color: Color:
For each solution with a pH less than 6 or greater than 8,
write a net ionic equation that accounts for the observed pH.
explain why the color observed with bromcresol green for each ofthe four solutions is resonable given the ph
