I have a question about phosphor supplements which come in tablet form which are dissolved in water before consuming.
I am currently taking these tablets (dissolved in tap water) which are Sodium Acid Phosphate.

I am concerned that these tablets are causing enamel erosion.
Am I right? What is the acidity of this chemical when dissolved in a glass of water?

Hard to say not knowing in detail what it really is. Assuming NaH₂PO₄ pH should be around 4.7, Coca Cola is more acididc (about 4.0), some fruit juices will go even lower.

You might have a concern, if you get this stuff on your teeth, and don't brush afterward.  People tend to forget about tooth enamel erosion by acids, they think, "No sugar, no problem."  And they end up surprised when their late night sips of artificially sweetened cranberry juice, has seriously eroded their teeth enamel.

The Phosphate acids are actually a lot better for your teeth than most acidic beverages.
Because your teeth also are composed of phosphate and so the phosphate ion in your tablets can reduce the damage the acid can do (common ion effect). 

Although it will still have a negative effect overall, I would predict it wouldn't be as bad as a glass of orange juice.

After taking the phosphates for 3 years and noticing the erosion, I think that the acids have been "eating away" over time.
However, I think that brushing straight after consuming them will go a long way in diminishing the damage.


Your answers have been very helpful in minimizing my concern over taking the phosphates.
Much thanks.
