Answer:

D

Explanation:

7 is neutral on a PH scale. Anything less is an acid and anything higher is a base. A Ph scale goes from 1-13. 8.4-7=1.4. This is a small change so it is considered a weak base. Can I get brainliest?

Answer:

D.A weak base

Explanation:

The pH of a weak base falls somewhere between 7 and 10. Like weak acids, weak bases do not undergo complete dissociation; instead, their ionization is a two-way reaction with a definite equilibrium point. While strong bases release hydroxide ions via dissociation, weak bases generate hydroxide ions by reacting with water. Ammonia (NH3) and methylamine (CH3NH2) are examples of weak bases.
