Answer:
the correct answer is B it is changeable
Explanation:
Science knowledge may change due to the development of new technics for observing investigations also through new ways of thinking or framing the questions asked.
Acids are solutions/substances that tend to break off to make a hydrogen (H+) ion when placed in an aqueous solution; i.e. solution with water as its solvent.
Bases, on the other hand, produce a hydroxide ion (OH-) when placed in an aqueous solution.
Thus, by definition, we can safely assume that a solution containing a large number of hydroxide ions is considered a base.
