Indicate whether each of the following compounds will gave an acidic, basic or neutral solution when dissolved in water. Clear All ammonium bromide barium nitrite barium iodide potassium bromide The pH will be less than 7. The pH will be approximately equal to 7. The pH will be greater than 7.

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.
