PLEASE HELP <br> What is the pH of a weak acid solution that has an [H+] of 2.1 × 10^–6 M
sveticcg [70]

Answer:

pH ( potential Hydrogen ) is a negative logarithm of molar concentration of hydrogen ions.

pH =  -  log[H {}^{ + } ]

therefore:

pH =  -   log(2.1 \times  {10}^{ - 6} )  \\ { \boxed{pH = 5.68}}

A cube of gold-colored metal with a volume of 64 cm has a mass of 980 g. The density of pure gold is 19.3 g/cm³. Is the metal pu
Xelga [282]

Answer:

No, the metal is not pure gold because density is equal to mass divided by volume and in this case we end up with about 15.3, making this metal less dense than gold.

The pH of a solution of propanoic acid is measured to be . Calculate the acid dissociation constant of propanoic acid. Round you
Genrish500 [490]

The given question is incomplete. The complete question is:

The pH of a 0.98 M solution of propanoic acid is measured to be 2.43. Calculate the acid dissociation constant of propanoic acid. Round your answer to two significant digits.

Answer: The acid dissociation constant of propanoic acid is 1.4\times 10^{-5}

Explanation:

CH_3CH_2COOH\rightarrow CH_3CH_2COO^-+H^+

 cM                                0             0

c-c\alpha                           c\alpha          c\alpha

So dissociation constant will be:

K_a=\frac{(c\alpha)^{2}}{c-c\alpha}

Give c= 0.98 M and pH = 2.43

pH=-log[H^+]

2.43=-log[c\times \alpha]

2.43=-log[0.98\times \alpha]

3.72\times 10^{-3}=0.98\times \alpha

\alpha=3.79\times 10^{-3}

K_a=\frac{(0.98\times 3.79\times 10^{-3})^2}{(0.98-0.98\times 3.79\times 10^{-3})}=1.4\times 10^{-5}

The acid dissociation constant of propanoic acid is 1.4\times 10^{-5}
