Analyze reactions 44 and 45, and write the similar reactions which may be obtained with either of the metals, calcium, strontium, barium, and magnesium. What theory of the constitution of the metallic hydrates do these reactions suggest V 4. In what respects do the hydrates Ca = O2-Ha and Mg = Os= H, differ from K-O-H and Na-O-H? 5. Analyze reactions 46, and show that the principal products must be regarded as hydrates. Name the class of compounds to which the other products and factors belong. 6. State the third theory which is held in regard to the constitution of the hydrates, and write the symbols of the different hydrates according to this view. Also bring these symbols into comparison with those of the same compounds written after the other two plans, and show by means of graphic symbols how far these forms are arbitrary, and how far they represent fundamental differences. 7. In what sense may the solution of ammonia gas in water be regarded as an hydrate? Write reactions 46, using ammonic hydrate instead of the hydrates of sodium, potassium, and barium. 8. In what relation do the metallic oxides stand to the hydrates? Define the term base. 9. Define the term salt, and illustrate your definition by examples. 10. Define the term acid. How does an acid differ from a metallic hydrate? Is an acid necessarily an hydrate? What two classes of acids may be distinguished? 11. What is the distinction between an acid and a basic radical. How are they related to the two hydrogen atoms of water? Assuming that there is no difference between these two atoms in the original molecule of water, does not the replacement of one of the atoms by a radical of either class alter the relations of the second? Is there not an...
