6. The compound of sodium with hydrogen, sodium hydride, is ionie, NaH. (a) What is the Lewis electron dot structure of hydride ion? (b) When sodium hydride is placed in water, hydride ion is converted to hydrogen, H,, and the resulting solution has pH > 7 and turns red litmus paper blue. Write a balanced equation showing the reaction of sodium hydride with water. (c) Is hydride ion an acid or a base? What is the relationship of hydrogen, H,, to hydride ion? (d) Hydride ion reacts with an alcohol, such as ethanol, in exactly the same way as it does with water, generating hydrogen as one of the products. Complete the following equation. CH,CH,OH + Na*H
