Which of the following compounds are acidic (A), basic (B), or relatively neutral (N)

Which of the following solutions would have the highest pH? Assume that they are all 0.10 M in acid at 25°C. The acid is followed by its K, value. HF, 3.5 x 104 O HNO₂, 4.6 x 10 O HCN, 4.9 x 10-10 O HCHO, 1.8 x 104 O HCO₂, 1.1 x 10-²

Calculate the pH of the solution. Assume 5.0 L of solution. You must identify the type of solution before calculating the pH. Express all pH values to two decimal places. 0.190 moles NH3 and 0.120 moles HCl K(NH3) = 1.8 x 10-5
