    Where can I buy chemicals?

    Where can I buy chemicals, preferably on Kowloon side?

    It's not inspired by 'Breaking Bad', more by some food adventures. I am looking for sodium chloride (NaOH) and ascorbic acid (vitamin C - 100g is way more then enough).

    Are you sure you want to use sodium hydroxide for food? Isn't it caustic soda?

    I believe you mean NaCl ( sodium chloride) not sodium hydroxide (NaOH) which caustic acid as this is very corrosive and dangerous even at low concentration ie, 1 molar

    NaCl ( sodium chloride) is common salt in inpure form (é¹½/yim)

    C6H8O6 ascorbic acid (抗壞血酸/hang wai huet shuen)

    another one is try is Phenylpthalein, try to use to too much as a prank,

    I seen a store on jervious rd near sheung wan municipal building that sells lots of food colouring and additives, best to try there firsy

    100% sure it's NaOH = sodium hydroxide. It's required for: http://en.wikipedia.org/wiki/File:Laugengeb%C3%A4ck.JPG

    I think you can also use sodium bicarbonate and cook it. But NaOH works well at room temperature.

    I believe you require lye water which is very different from pure form sodium hydroxide, which is dangerous, lye water is called 梘水 is used in both eastern cooking and westerner cooking

    Of course I need it liquefied in water. But see, when I have NaOH I can combine it with water to get what i want, which is a 3.5% NaOH solution. That is the common standard at room temperature for pretzels.

    I think baking soda breaks into NaOH when cooked, I never tried that. I prefer to work at room temp. I tried it with some NaOH on hand and it worked very well.
