The [[chemical compound]] '''sodium alginate''' is the [[sodium]] [[salt]] of [[alginic acid]]. Its [[empirical formula|empirical chemical formula]] is NaC<sub>6</sub>H<sub>7</sub>O<sub>6</sub>. Its form as a [[natural gum|gum]], when extracted from the cell walls of brown [[algae]], is used by the foods industry to increase [[viscosity]] and as an [[emulsifier]]. It is also used in indigestion tablets and the preparation of dental impressions. Sodium alginate has no discernible flavor. |

Another major use of sodium alginate is [[reactive dye printing]], where it is used in the [[textile industry]]. |

==Radioactivity within the body== |

Sodium alginate is a good chelator for pulling radioactive toxins such as iodine-131 and strontium-90 from the body which have taken the place of their non-radioactive counterparts.<ref>Sutton, A., Harrison, G.

Sodium alginate is also used in immobilizing enzymes by inclusion. IT helps plants grow. IT retains nutrients and mositure and helps slow the release of nitrogen into the soil. There are less fertilizer dead zones if people use sodium aliginate |
