Initial moles of CH₃COOH = 1.00 x 0.0100 = 0.0100 mol
Initial moles of CH₃COONa = 1.00 x 0.100 = 0.100 mol
Let a be the volume of HNO₃ that must be added
Moles of HNO₃ added = a/1000 x 10.0 = 0.01a mol
CH₃COONa + HNO₃ => CH₃COOH + NaNO₃
Moles of CH₃COOH = 0.0100 + 0.01a
Moles of CH₃COONa = 0.100 - 0.01a
pH = pKa + log([CH₃COONa]/[CH₃COOH])
= pKa + log(moles of CH₃COONa/moles of CH₃COOH)
5.05 = 4.75 + log((0.100 - 0.01a)/(0.0100 + 0.01a))
log((0.100 - 0.01a)/(0.0100 + 0.01a)) = 0.3
(0.100 - 0.01a)/(0.0100 + 0.01a) = 10^0.3 = 2.0
0.03 a = 0.08
a = 2.67
<span>Volume of HNO3 = a = </span>2.13 mL
54 mL Ba(OH)2x(0.101 mol Ba(OH)2/1000 mL) x (2 mol OH-/ 1 mol Ba(OH)2 ) = 0.0109 mol OH-
0.0109 mol OH-x (1mol HCl/ 1 mol OH- ) = 0.0109 mol HCl
0.109 mol HCl/(0.130 mol/L HCl) = 0.0839 L HCl
0.0839 L HCl * 1000mL = 83.9 mL of 0.130 M HCl
Answer:
3Ag^(+) + 3Cl ^(-) --> 3AgCl (s)
Explanation:
Full ionic equation:
3Ag^(+) + 3NO3^(-) + Al^(+3) + 3Cl^(-)-->
3AgCl (s) + Al^(3+) + 3NO3^(-)
Spectator ions 3NO3^(-) & Al^(+3) can be left out in the net ionic equation.
