which of these substances is the least acidic?\n solution a, poh = 1.5\n solution b, poh = 7.0\n solution c, poh = 13.5
Answer
Answer:
Solution A, pOH = 1.5
Explanation:
Step1: Recall pH - pOH relationship
pH + pOH=14, so pH = 14 - pOH
Step2: Calculate pH of solution A
pH_A=14 - 1.5=12.5
Step3: Calculate pH of solution B
pH_B=14 - 7.0 = 7.0
Step4: Calculate pH of solution C
pH_C=14 - 13.5=0.5
Step5: Determine least acidic
Lower pH means more acidic. Higher pH means less acidic. Since 12.5>7.0>0.5, solution A is the least acidic.
