phenolphthalein Then add 1 M NaOH to fade pink. Then dilute this to 100 ml with distilled water. From this volume i take 50 ml , add 1 drop of phenolphthalein and 8 ml combined reagent and after 10 minutes read on 880 nm. I did a calibration curbe and table with formula included. ...
The pH of 0.1 mol / L solution is 13.5. [1] Potassium hydroxide has the universality of alkali, which has the following properties: 1 The color reaction can make litmus test solution turn blue and phenolphthalein test solution turn red. 2. React with acid, such as hydrochloric acid, ...
(1). The acid solution can try purple litmus red, the color of colorless phenolphthalein. (2). The alkali solution can make the purple litmus blue. 10. in the study of elements, two depend on: (1). The element type depends on the nuclear charge number (i.e. number of electrons in...

Potassium Acetate is an inorganic salt also known as potassium oxalate, diuretic salt, acetic acid, or potassium salt, with the molecular formula CH3COOK and the structure shown below. It is a deliquescent white crystalline solid with a faint acetic acid odour and a melting point of 292...
We need to start with the structure of water. Now, you might imagine that a molecule with the formula H2O would have its atoms arranged in a straight line, like this: H–O–H. But it doesn’t, and the reason it doesn’t is that the oxygen atom in the middle has two pairs of el...
This chemical’s molecular formula is C24H27N5O2 and molecular weight is 417.504. It is a potent H3K27me3 demethylase inhibitor.[1] Figure 1 the molecular formula of GSK-J4 Indication In 2013, the first selective and potent inhibitor of JMJD3/UTX demethyltransferase activity, GSK-J4, was ...
