Which is the best acid to use in the preparation of a buffer with ph = 3.3?

Chemistry

A combination of a weak acid and its conjugate base which is a mix of a weak base and its conjugate acid is so-called a buffer solution or a buffer. Buffer solutions repel a change in pH when small amount of a strong acid or a strong base are additional. Therefore, the best acid to use in the preparation of a buffer with pH=3.3 is HNO₂(Ka = 4.5 * 10 ⁻⁴). The pH of a buffer is contingent on the ration base / acid relatively than on the particular concentration of a precise solution. The precise ratio of the base to the acid for an anticipated pH can be determined from the Ka value and the Henderson HasselBalch equation.

H2O has a mc021-1.jpgHvap = 40.7 kJ/mol. What is the quantity of heat that is released when 27.9 g of H2O condenses?
babymother [125]

Energy released from changing the phase of a substance from the gas phase to liquid phase can be calculated by using the specific latent heat of vaporization. The heat of fusion of water at 0 degrees Celsius is 40.7 kJ/mol. Calculation are as follows:<span> </span>


Energy = 27.9 g (1 mol / 18.02 g) x 40.7 kJ/mol


Energy = 63.09 kJ

What is keq for the reaction 2so2(g) + o2(g) 2so3(g)? apex?
Dennis_Churaev [7]
The  keg for the reaction
2  SO2(g) + O2(g)   →  2  SO3(g)  is

 Keg =  [SO3]^2/ {(SO2)^2 ( O2)}

Keg (equilibrium constant)  is the ratio of  of equilibrium  concentration  of the product   raised  to the power  of their  stoichiometric  coefficient  to the  equilibrium  concentration  of the reactant  raised  to the power  of  their stoichiometric  coefficient.
