According to Henderson–Hasselbalch Equation,
pH = pKa + log [CH₃COO⁻] / [CH₃COOH]
As,
Ka of Acetic Acid = 1.8 × 10⁻⁵
pKa = -log Ka
pKa = -log 1.8 × 10⁻⁵
pKa = 4.74
So,
pH = 4.74 + log [0.85] / [0.45]
pH = 4.74 + log 1.88
pH = 4.74 + 0.276
pH = 5.01
Answer:
(CPI) Consumer Price Index
Explanation:
A consumer price index measures changes in the price level of a weighted average market basket of consumer goods and services purchased by households. A CPI is a statistical estimate constructed using the prices of a sample of representative items whose prices are collected periodically.
If you mix Ammonia as well as Hydrogen chloride, you will get ammonium chloride. It is given by NH3 (g) + HCl (g) → NH4Cl(s).

Hello!
In this case, for the separation of the benzene-toluene mixture, we can use the following mole balances including the given mole fraction at each stream per species:
That can be solved by using a solver for P1 (benzene-rich flow) and P2 (toluene-rich flow):
Best regards!
