Hello everyone. I have a question about the sodium alginate (NaC6H7O6)n. Recently, sodium alginate is widely used for fabricating edible bottle. And I also try to utilize sodium alginate for controlling the viscosity of water. I found that with small amount of sodium alginate powder in DI water (0.1 ~ 1.0 wt%), I could get more viscous water which is still fluent, not like edible bottle. However, I'm not sure how the sodium alginate increases the viscosity of water. What I know is that the sodium alginate is ionized into sodium cation and else. But I don't think that is the only reason that makes water viscous. Will you let me know the molecular equation of reaction between sodium alginate and DI water?? Thank you so much!!!
