What is the role of trisodium phosphate when added to alginate impression material?

Show Answers

Extends the working time of the alginateFunctions as a setting acceleratorTriggers the setting processEnhances the gel's strengthImproves the material's elasticity

Explanation

Trisodium phosphate is used to lengthen the working time of alginate impression materials, allowing more time for manipulation before the material begins to set. It does not act as an accelerator, initiate setting, or improve gel strength.
