Textbook Problem J.9

[Madilyn Schindler 3E]

Could someone please explain this?

Identify the salt that is produced from the acid–base neutralization reaction between (a) potassium hydroxide and acetic acid, CH3COOH;CH3
COOH; (b) ammonia and phosphoric acid; (c) calcium hydroxide and bromous acid; (d) sodium hydroxide and hydrosulfuric acid, H2S (both H atoms react). Write the complete ionic equation for each reaction.

[Tanya Nguyen 1B]

For this problem, you'll need to write an equation for the given acids and bases with the product of salt and water (acid+base->salt+water). So for (a) potassium hydroxide is K(OH) (base) and acetic acid is CH3COOH (acid). The equation for this reaction should be K(OH) + CH3COOH -> CH3OOK + H2O. The salt would be CH3OOK.

[Katherine_Douglas_1F]

The key to these problems is isolating out the OH- and H+ to form water and then pairing whatever is left together. For the rest of the problems, it would go as follows:

c) Ca(OH)2 +2HBr ----> 2H2O + CaBr2

d) 2NaOH + H2S ----> 2H2O + Na2S
