Hello there. I was reading something on the affect sodium hydroxide has on ordinary starch from plain flour. I read that sodium hydroxide can change the physical and chemical properties of starch. I conducted an experiment where I mixed 2mol and 8mol sodium hydorxide with plain flour in a test tube. When I added the colour indicator (Iodine solution) to this mixture, there was no colour change. I was wondering if this is due to the sodium hydroxide changing the chemical properties of the starch or if I made a mistake somehow.
Thanks guys, any help or response will be appreciated
