Calculate the hydrogen-ion concentration [H+] for the aqueous solution in which [OH–] is 1 x 10–11 mol/L. Is this solution acidi

valina [46]

(H+)(OH-) = Kw
kw= 1 x10^-14
OH-= 1 x10 ^-11
(H+)= KW / OH-

concentration of H+ = (1x10^-14) /.(1 x 10 ^-11) = 1 x10 ^-3

Ph= -log (H+)

PH=-log ( 1 x 10 ^-3) = 3 therefore the solution is acidic since the PH less than 7

Using dimensional analysis convert 238.0 cm3 to L

Bezzdna [24]

Answer:

= 0.238 L

Explanation:

From the given information:

To convert cm³ to L(liter), we utilize the advent of a unit fraction that comprises a liter in the upper part of the fraction(numerator) and a cubic centimeter in the lower part of the fraction(denominator)

Recall that:

1000 cm³ = 1 liter

∴

238.0 cm³ = $\dfrac{238.0 \ cm^3}{1} \times \dfrac{1 \ L}{1000 \ cm^3}$

= 0.238 L
