The temperature for each solution is carried out at approximately 297 K where Kw=1.00 x 10-14-   a) 0.20 g of hydrogen chloride (HCl) is dissolved in water to make 4.5 L of solution. What is the pH of the resulting hydrochloric acid solution? Express the pH numerically to two decimal places.   b)  0.70 g of sodium hydroxide (NaOH) pellets are dissolved in water to make 3.0 L of solution. What is the pH of this solution?   Express the pH numerically to two decimal places.

it pt Calculate the pH of a solution that has an ammonium chloride concentration of 0.042 M and an ammonia concentration of 0.047 M. pH = Ky=1.8 x 10-

The pH of blood is 7.4. What is the ratio (to one decimal place) of bicarbonate (conjugate base) to carbonic acid (weak acid) in the blood's buffering equilibrium? Note, the K₂ of carbonic acid is 4.27 x 10-7. Write your answer this way: # to 1 Done Clear Incorrect. The ratio is 10.7 to 1, indicating that there is 10 times more bicarbonate than carbonic acid. Enter the correct answer.

the solution has to be acidified before testing for Ag+ ions. To make sure that the solution is acidic, what should be done?     Apply a drop of the solution to red litmus paper to see if it turns blue.     Apply a drop of the solution to blue litmus paper to see if it turns red.     Apply a drop of the solution to pH paper to see if the pH is above 7.     Apply a drop of the solution to your tongue to see if it tastes sour.

A conjugate acid (HA) and its conjugate base (A") is mixed to make buffer solutions. When 0.50 mol HA and 0.50 mol A are mixed into 1.00 L solution, the pH of the solution is 4.87. Calculate the pH of the buffer solution by mixing 0.25 mol HA and 0.75 mol A into 1.00 L solution. Your pH value should have the form of XXX, XX.X, X.XX or 0.XXX.
