When calcium nitrate, Ca(NO3)2, dissolves in water, it dissociates into its ions. We can represent that process by the following equation: Ca(NO3)2(s) → Ca2+(aq) + 2NO3-(aq) When 1.5 mol calcium nitrate dissolves in water, how many moles of ions should be present in solution?

Consider a culture medium on which only gram-positive organisms such as staphylococcus aureus colonies can grow due to an elevated nacl level. a yellow halo surrounds the growth, indicating the bacterium fermented a sugar in the medium, decreasing the ph as a result and changing the color of a ph indicator chemical. this type of medium would be referred to as a differential and enrichment culture.
