چکیده
The use of natural materials began to be developed on a large scale in chemistry. Natural substances are safe use, easy find, and cheaper. Biological indicators volumetric titration the focus experts. This study presented visualization alkalimetric weak acid with strong base addition indicators. Hibiscus rosa-sinensis L. Clitoria ternatea flowers were used as for diprotic acid, namely oxalic base, sodium hydroxide. phenolphthalein indicator was chosen an compare. Maceration flower crowns aimed obtain biological extracts. held three times flower, phenolphthalein. crown extract gave pink color solution. There change clear when titrated. indicated endpoint titration. showed relatively similar curve during result that two extracts had same function base.

The Determination of Inorganic Phosphate in Urine by Alkalimetric Titration,
In an investigation of the excretion of phosphate and other substances in short periods (chiefly of 1 hour) now being conducted in this laboratory, it has been necessary to make many inorganic phosphate determinations with limited quantities of urine. In most instances the accuracy possible with colorimetric and nephelometric methods has been sufficient, and, after a considerable amount of time...

Data visualization tools can take existing statistics and re-express them in ways that facilitate interpretation by a variety of audiences ranging from the sophisticated “power user” to the novice. Because these tools can expand a program’s audience dramatically, it is vital to develop tools that “tell the complete story,” for example, including measures of reliability along with point estimate...
