I want to use hcl instead of acetic acid becouse acetic acid give bad irresistable smell..so is it possible that i can take hcl solution?is 2.5gm of chitosan will disslove in 500ml Hcl solution?
Well, that largely depends on the molecular weight or viscosity of your chitosan. For chitosan of viscosity upto 200cP, you should be able to do that. However, for viscosity above 200cP, I don't think you can.
