Will Drinking Nuun Added To Water Or Propel Hydrating Water

Will drinking Nuun added to water or Propel hydrating water affect the ph balance in esophagus or stomach when having Brovo ph testing? Will they change the results of the test? Nuun dissolves like alka-sellser and they both leave salty taste in mouth, like bicarbonate soda. I don’t understand the terminology use on the ingredients labels.
