Calculate the pH of the final equilibrium mixture in each of the following solutions:

1. 10 mL of 0.005 M HNO₃ are mixed with 5 mL of 0.006 M NaOH [answer: pH=2.87]

2. One mole of HCl is mixed with one mole of ammonia (NH₃; k_b=1.76*10^-5) to form one liter aqueous solution. [answer: pH=4.62]

3. 0.5 moles of HCl is mixed with one mole of ammonia (NH₃; k_b=1.76*10^-5) to form one liter aqueous solution. [answer: pH=9.24]

4. One mole of hydrocyanic acid (HCN; k_a=6.2*10^-10) is mixed with one mole of potassium hydroxide (KOH) to form a one liter aqueous solution. [answer: pH=11.60]

5. One mole of hydrocyanic acid (HCN; k_a=6.2*10^-10) is mixed with 0.5 mole of potassium hydroxide (KOH) to form a one liter aqueous solution. [answer: pH=9.21]

6. 0.35 moles of ammonia (NH₃; k_b=1.76*10^-5), 01. mole ammonium nitrate (N₃H₄O₃), and 0.2 mole nitric acid are mixed to form one liter aqueous solution. [answer: pH=8.93]
