A solvent is a substance that can dissolve other substances. Water is a solvent because it is a polar molecule so it will attract other charged particles such as ions and other polar molecules such as glucose. Therefore chemical reactions can take place in solution since these chemicals dissolve in water. This is because the negatively charged oxygen atoms in the water molecules attract each of sodium ion and the positively charged hydrogen atoms attract on each of negatively charged chloride ion. Sodium Chloride and Potassium Bromide were soluble in distilled water.
