The authors describe the use of the quantab test strip for determining the chloride content of water extracted from sea-dredged aggregates, and compares the results with those obtained by ...
water above 55°C (131°F), and becomes anhydrous at 121°C (250F). As a cheap, soluble salt of barium, barium chloride finds wide application in the laboratory. It is commonly used as a test for sulfate ion. In industry, barium chloride is mainly used chiefly in the synthesis of ...

A.If you are just checking to make sure that you don't have too much chloride as a contaminant in your chrome solution, I think the easiest method is a titration; but you don't need an electrode- just a good eye and some good clean glassware. I'm feeling generous, so I'll just ...
The Cl− concentration in the real sweat was also measured by the standard titration method. The measured value is 32.94 ± 5 mM confirming the good performance of the sensor. The results obtained clearly show the ability of the proposed sensor platform to quantify sweat chloride with very ...
The pore solution of cylindrical paste specimens was collected according to the expression method proposed by Barneyback and Diamond [20]. The collected pore solution was stored in plastic bottles and sealed immediately to avoid water evaporation and carbonation. An inductively coupled plasma optical em...
This product is easily soluble in water and ethanol but insoluble in ether, petroleum ether, benzene and carbon disulfide. It has a low toxicity with LD50 (rat, oral) being 3400 mg/kg. Production method (1) Continuous method for preparation of choline chloride solution: continuously send the...
For this approach, the chloride binding capacity of each binder type is examined by measuring the residual-free chloride content in the pastes using the titration method. Half-cell potential test was carried out to investigate the probability of steel corrosion that may happen due to the content ...
9.3.2Shinoda’s Test Four pieces of magnesium filings are added to theethanolic extract, followed by a few drops of concentratedhydrochloric acid. A pink or red color indicates the presence offlavonoids. 9.3.3Sodium Hydroxide Test About 5mg of the compound is dissolved in water, then warmed, ...
Influence rules of adding single fly ash,single silica fume,and compound of fly ash and silica fume as well as age on the performance of mortar solidifying chloride were studied through chemical titration method. 采用化学滴定的方法,研究了单掺粉煤灰、单掺硅灰、粉煤灰与硅灰双掺以及龄期对砂浆固化...
