The student is now told that the four solids, in no particular order, are barium chloride (BaCl2), sugar (C6H12O6), butanoic acid (C3H7COOH), and potassium bromide (KBr). Assuming that conductivity is correlated to the number of ions in solution, rank the four substances based on how well a 0.20M solution in water will conduct electricity.
Find the volume (mL) and pH of 0.0588 M KOH needed to reach the equivalence point(s) in titrations of the following.
what mass of this substance must evaporate in order to freeze 230g of water initially at 16 degrees? the heat of fusion
