How can I justify a drop in viscosity of alginate solutions by addition of monovalent salts such as sodium chloride?

I measured the viscosity of both pure alginate at 3% (w v-1) and a mixed solution of alginate at 3% (w v-1) +1% (w v-1) sodium chloride. Interestingly, instead of ending up with an enhancement in...
