Answer:

✓ It will react with hydrochloric acid to make a salt.

  • An acid combined with a base makes a salt!

✓ It has a bitter taste.

  • Bases are often bitter, whereas acids are often... acidic? Like citrus or coffee.

✓ It has a pH of 9.

  • Since it's basic, this is a safe assumption. Remember: Basic = pH over 7.

☓ It has a pH of 5.

  • No! It's basic, not acidic!

✓ It will produce OH- ions when mixed into a water solution.

  • Bases are defined by producing OH- ions in solution! Acids produce H+ ions instead. This is part of the definition: just memorize it.
