2. Hardness Standard Solution
HARD(CaCl
2
)-200 solution is a solution of calcium chloride (CaCl
2
)
equivalent to 200 ppm calcium carbonate that is used for the hardness
calibration: Order HARD-200.
C. Titration Reagent Solutions
Titration reagents are required for all conductometric titrations —
alkalinity, hardness and LSI. LSI titrations require both alkalinity and
hardness reagents. Reagents are available in 2 oz. and quarts/liters.
1. Reagent: A1
Reagent: A1 is a ≤1%WV solution of sulfuric acid (H
2
SO

-1) required for
alkalinity titration: Order H2SO4-1.
2. Reagent: C1
Reagent: C1 is a ≤3%WV solution of hydrochloric acid (HCl-3) required
for hardness titration: Order HCL-3.
3. Reagent: H1
Reagent: H1 is a ≤4%WV solution of pH buffer sodium hydroxide (NaOH)
required for hardness titration: Order NAOH.
4. Reagent: H2
Reagent: H2 is a low concentration ≤5%WV solution of
Ethylenediaminetetraacetic acid (EDTA) required for hardness titration:
Order EDTA-LC.
5. Reagent: H3
