(NH4) 2SO4 ammonium sulfate ammonium sulfate Molecular sieves, such as type 4A molecular sieves, are sodium aluminosilicate and zeolite 5A is a solid adsorbent for the separation of large and small molecules from calcium aluminosilicate Phenolphthalein C20H14O4 3, 3- (4- hydroxyphenyl) -1 (3H...
Chemical equations can be further shortened if we use the chemical formulae of the reactants and products. So, if we were to write the above chemical reaction using the formulae of magnesium, oxygen and magnesium oxide, it would be written as follows – Mg + O2→ MgO Now, if you count...
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...
[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, sulfuric acid, nitric acid and hydrogen sulfide. ...
(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...

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. ...
There are actually lots of pH indicators, with a wide variety of colour changes.Phenolphthalein, for example, is bright pink in alkali, and colourless in acids.Bromocresol purple(they have such easy-to-spell names) is yellow in acids, and violet-purple in alkalis. ...
