I assume from your question that the cell in question has an intracellular salt concentration of 2%. This would make the cell abnormal as a human cell inasmuch as human cells have a salt concentration of approximately 0.9%.
Distilled water has no salt or solute, and therefore represents the most extreme example of a hypotonic solution (a solution having a salt concentration lower than that normally found in the human blood, cells and fluids).
A 2% salt solution would be hypertonic.
A 0.9% salt solution would be isotonic.
Therefore, the answer to your question is that a cell with 2% tonicity in distilled water is immersed in a hypotonic solution. The result would be migration of water across the cell membrane into the intracellular fluid, distending and eventually rupturing and destroying the cell...a process called lysis.
