QUESTION 4

A substance that produces OH– ions in solution is a(n)_____.


A)acid


B)salt


C)base


D)alcohol

Answer 1

Answer: acid

Step-by-step explanation:

In this reaction, sodium hydroxide (NaOH) disassociates into sodium (Na+) and hydroxide (OH-) ions when dissolved in water, thereby releasing OH- ions into solution.

Answer 2

Bases are the chemical compounds which give out
`\bold{OH^-}` ions when dissolved in aqueous solution or water.

Step-by-step explanation:

In science, bases are substances that show the following characteristic:

• In watery arrangement, discharge hydroxide
  `\bold{(OH^-)}` particles.
• It is elusive/slippery to the touch.
• It has bitter taste.
• It changes the shade of litmus paper (e.g., turn red litmus paper blue).
• It responds with acids to shape salts.
• It advances certain compound responses (base catalysis).
• It receives protons from any proton contributor or contain totally or halfway displaceable
  `OH^-` particles.
