When NaCl is dissolved in water, the sodium ion becomes:AoxidisedBreducedChydrolysedDhydrated

When NaCl is dissolved in water, then due to the high dielectric constant of water, water dissosciates the NaCl molecule into Na 
+
  ions and Cl 
−
 ions. Each Na 
+
 ion and Cl 
−
  ion is surrounded by multiple water molecules. This process is called as hydration of NaCl. Thus, Na 
+
 ion is said to be hydrated.
