Answer: 60 minutes per hour, sixty miles per hour, therefore, one mile per minute.
Explanation:
Answer:
<u>The pH at equivalence is 5.24 .</u>
Explanation:
Let us calculate -
millimoles of aniline = 160 x 0.3403 = 54.448
To reach equivalence , 54.448 millimoles HNO3 must be added,
V = 1086.79 mL HNO3 must be added
total volume = 1086.79 + 160 = 1246.79 mL
Concentration of [salt] = = 0.044 M
Now, at the equivalence or equivalent point ,
By solving the above equation , we get -
pH = 5.24
<u>Hence , the answer is 5.24 </u>
