Which of the following is NOT a characteristic of a strong acid and a strong base?
A. Has a [H+] higher than water
B. Is corrosive to most metals
C. Has a pH at the extreme end of the scale
D. Completely dissociates in water
Oh, of course, sorry. I am thinking it is C?
C is not right. The pH of strong acids is at the low(1 or less) end and pH of strong bases at the high end (13 or higher).
To determine which of the given characteristics is NOT a characteristic of a strong acid and a strong base, we can analyze each option.
Option A: "Has a [H+] higher than water"
To compare the acidity of a substance, we can look at the concentration of H+ ions. A strong acid indeed has a higher concentration of H+ ions than water. Therefore, this characteristic is commonly associated with strong acids rather than being NOT a characteristic.
Option B: "Is corrosive to most metals"
Both strong acids and strong bases can be corrosive to metals. They react with metal surfaces, leading to corrosion. Hence, this characteristic is not limited to only one of them and therefore is not the answer.
Option C: "Has a pH at the extreme end of the scale"
Strong acids and strong bases have very low and high pH values, respectively. The pH scale ranges from 0 to 14, with 0 being very acidic and 14 being very basic/alkaline. So, this characteristic does apply to both, making it NOT the correct answer.
Option D: "Completely dissociates in water"
This is a characteristic that strong acids and strong bases have in common. Both completely dissociate or ionize in water, which means they break apart into their component ions. Since this characteristic applies to both, it is NOT the correct answer.
Based on the analysis, the characteristic that is NOT associated with a strong acid and a strong base is:
C. Has a pH at the extreme end of the scale
