Hi everyone. I'm doing research with sodium alginate (NaC6H7O6) and I really need your help. Sodium alginate is a cell wall component of seaweed or brown algae. During the research, I read some pages telling that we can get alginic acid by dissolve sodium alginate in water. But what I think is that, if the NaC6H7O6 is dissolve in water, it will ionized and loss Na+. Then the solution will be a base, not an acid.... And I test the pH with sodium alginate solution and I got a pH 7 (Actually, I didn't dissolve much powder) Is it right that the solution of sodium alginate is a really acid???
