Detailed Product Description: | Product Code: 31410222516 Product Name: phenolphthalein Specifications: 1 Notes: 1 Category: (a) the use of chemical reagents sodium hydroxide is very extensive, in chemistry experiments, in addition to the reagents used outside, because it has a strong moisture absorption , can also be used as an alkaline desiccant. Caustic soda is widely applied in the national economy, many industrial sectors require caustic soda. Use caustic chemicals sector is the largest manufacturing, followed by paper, aluminum, tungsten refining, rayon, rayon and soap manufacturing. In addition, the production of dyes, plastics, pharmaceutical and organic intermediates, the regeneration of the old rubber, made of metallic sodium, water and inorganic salt electrolysis production, preparation of borax, chromium salts, manganese, phosphate, etc., but also the use of a lot of soda. Hydroxide for industrial use should be consistent with national standards GB 209-2006; industrial ion exchange membrane caustic soda should meet the national standard GB / T 11199-89; fiber with sodium hydroxide should meet the national standard GB 11212-89; edible hydrogen sodium oxide should meet the national standard GB 5175-85. Name: the color range of color indicator type indicator is not affected by an amount of, but the indicator itself is an acid or a base, to consume a certain color indicator titration agent, thereby increasing the measurement error. For monochrome indicator, the amount of excess acid copper Dongguan agent, will use the color range of the pH value decreases movement occurs direction will increase the titration error. For example: with 0.1mol / LnaOH titration 0.1mol / LHAc acid copper light stabilizers, pHsp = 8.5, range jump for pH8.70-9.00, titration volume if it is 50ml, drip 2-3 drops of phenolphthalein, about pH = 9 When red; if drops 10-15 drops of phenolphthalein acid copper brightener manufacturers, the red appeared 8:00 in pH =. Obviously the latter titration error is much greater. Indicator excessive amount, but also affect the color of acumen. For example: methyl orange as indicator Chang'an acid copper agent, titrated with NaOH HCl solution, the end of an orange, if the amount of excess methyl orange end acumen on the poor. Acid copper brightener acid copper supplier _ _ Jing Chi light dose of Bose equipment operators from Dongguan Changan Jing Chi Bose equipment operators offer.
