Two technicians were discussing hybrid organic acid technology​ (HOAT) coolants. Technician A stated that hybrid organic acid technology​ (HOAT) coolants use organic acid salts​ (carboxylates) that are abrasive to water pumps. Technician B stated that the pH of hybrid organic acid technology​ (HOAT) coolants is usually below 7. Which of the following about the scenario is​ true?
A. Only technician​ A's assessment is accurate.
B. Neither technician​ A's nor​ B's assessment is accurate.
C. Both technician​ A's and​ B's assessments are accurate.
D. Only technician​ B's assessment is accurate.

Respuesta :

Answer:

B. Neither technician​ A's nor​ B's assessment is accurate.

Explanation:

Technician A is wrong because HOAT use organic acid with a low silicate inorganic corrosion inhibitors and it doesn't damage water pump as it contains azole additive which is a copper corrosion inhibitor.

Technician B is wrong because all coolants operate at neutral or basic pH range (pH equal to or greater than 7).
