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>
Since the chemical definition of "stable" means close to having a full valence shell, the answer is 3d^10.
Hey there!:
<span>Reaction stoichiometry :
</span>
Number of moles NaHCO3 :
Molar mass NaHCO3 = <span>84.007 g/mol
</span>
n = m / mm
n = 2.50 / 84.007
n = 0.0297moles of NaHCO3
2 NaHCO3 + H2SO4 = Na2SO4 + 2 CO2 + 2 H2O
2 moles NaHCO3 ----------------- 1 mole H2SO4
0.0297 moles NaHCO3 ----------- moles H2SO4
moles H2SO4 = 0.0297 * 1 / 2
moles H2SO4 = 0.0297 / 2
= 0.01485 moles of H2SO4
Therefore:
Molarity ( H2SO4 ) = moles H2SO4 / volume
0.600 M = 0.01485 / V
V = 0.01485 / 0.600
V = 0.02475 L of H2SO4
hope this helps!
