Answer:

B. 3. 0×10^-4M

How much 5.50M NaOH must be added to 680.0 mL of a buffer that is 0.0215 M acetic acid and 0.0270 M sodium acetate to raise the
Lelu [443]

5.50M NaOH must be added to 680.0 mL of a buffer, The amount of NaOH  is mathematically given as

V=2.107mL

<h3>What is the volume of 5.50M NaOH?</h3>

Generally, the equation for Chemical Reaction is mathematically given as

CH3COOH+OH^{-} ⇄ CHCOO^{-} + H2O

Therefore

pka=-log(1.8*10{-5})

pKa=5-0.25527

pKa=4.3447

Hence

pH=pKa+log\frac{CH3COO}{CH3COOH}\\\\0.75=4.7447+log\frac{0.01564+x}{0.01428-x}

x=0.0115898

Volume of NaOH

V=0.0021072L

V=2.107mL

A mixture of uneven distribution and easy separation is called. homogeneous a solution heterogeneous a standard
Blizzard [7]

The solutes dissolves in solvent results in the formation of a solution.

Those mixtures in which the components of mixture are uniformly distributed throughout the mixture are said to be homogeneous.  

Those mixtures in which the components of mixture are not uniformly distributed throughout the mixture are said to be heterogeneous.  

Those solutions whose concentrations are accurately known are known as standard.

Hence, a mixture of uneven distribution and easy separation is heterogeneous.
