Methyl orange is an indicator (buffer solution) that is red in its acidic form (HMO) and orange in its basic form (MO-). A solution at pH 5.0 contains methyl orange. Calculate the ratio of concentrations [MO-]/[HMO] in this solution. pKa methyl orange = 3.9
1. Calculate the cell emf for the following reaction: 2Ag+ (0.10 M) + H2 (1.0 atm) Æ 2Ag(s) + 2H+ (pH = 8.00)
A buffer solution is prepared by mixing 500.0 mL of 0.600 M CH3COOH with 500.0 mL of a 1.00 M CH3COONa solution. What is the pH of the resulting solution?
2. What is the molar solubility product of Ag3PO4 in 0.20 M AgNO3? Ksp of AgNO3 = 1.8 x 10-18
