Introduction

Brand: Erun environmental protection

Name: Water quality phenolphthalein alkali determination reagent utensils

Model Number:ERUN-PA40

Parameters: phenolphthalein alkalinity (Acid-base titration)

Phenolphthalein alkalinity is caused by all the hydroxide ions and half of the carbonate content in the water. Phenolphthalein alkalinity is the amount measured when phenolphthalein is used as an indicator. The endpoint pH value is 8.3. ERUN- produced by Erun Environmental Protection The PA40 water quality phenolphthalein alkalinity determination reagent container contains all reagents and instruments for detecting phenolphthalein alkalinity, and can directly test water quality and water samples.

Features

Test Notes:

1, alkalinity measurement unit (mmol/L), with equal monovalent ion as the basic unit. 

2, If the residual chlorine content in the water sample is more than 1 mg/L, the color of the indicator will be affected. 1~2 drops of 0.1 mol/L sodium thiosulfate solution can be added to eliminate the influence of residual chlorine (Cl2).
