A buffer solution is composed of 4.00 4.00 mol of acid and 3.25 3.25 mol of the conjugate base. If the p K a pKa of the acid is
Reika [66]

<u>Answer:</u> The pH of the buffer is 4.61

<u>Explanation:</u>

To calculate the pH of acidic buffer, we use the equation given by Henderson Hasselbalch:

pH=pK_a+\log(\frac{[\text{conjuagate base}]}{[\text{acid}]})

We are given:

pK_a = negative logarithm of acid dissociation constant of weak acid = 4.70

[\text{conjuagate base}]} = moles of conjugate base = 3.25 moles

[\text{acid}]  = Moles of acid = 4.00 moles

pH = ?

Putting values in above equation, we get:

pH=4.70+\log(\frac{3.25}{4.00})\\\\pH=4.61

Hence, the pH of the buffer is 4.61

Explain why the benzene molecule usually reacts with electrophiles<br>​
Genrish500 [490]

Answer:

Explanation:Because of the delocalised electrons exposed above and below the plane of the rest of the molecule, benzene is obviously going to be highly attractive to electrophiles - species which seek after electron rich areas in other molecules.

An aqueous solution of a soluble compound (a nonelectrolyte) is prepared by dissolving 33.2 g of the compound in sufficient wate
Alecsey [184]
M=n(pie)/RT
n=osmotic pressure(1.2 atm)
M=molar  of the  solution
R=gas  constant(0.0821)
T=  temperature  in  kelvin 25+273
M=[1.2atm /(0.0821L atm/k mol x  298k)]=0.049mol L
M= moles  of  the  solute/ litres  of solution(250/1000)
0.049=  y/0.25
moles  of  solute is therefore =0.01225mol
molar  mass=33.29 g/0.01225mol=2.7 x10^3g/mol
