**Week 3 Assignment: Acid-Base Equilibria** **pH of a Strong Acid and a Strong Base** **Understanding pH:** - The pH is a logarithmic scale used to indicate the hydrogen ion concentration, \([H^+]\), of a solution: \[ \text{pH} = -\log[H^+] \] - Due to the autoionization of water, in any aqueous solution, the hydrogen ion concentration and the hydroxide ion concentration, \([OH^-]\), are related to each other by the \(K_w\) of water: \[ K_w = [H^+][OH^-] = 1.00 \times 10^{-14} \] where \(1.00 \times 10^{-14}\) is the value at approximately 297 K. Based on this relation, the pH and pOH are also related to each other as: \[ 14.00 = \text{pH} + \text{pOH} \] **Exercises:** **Part A:** - A sample of 0.20 g of hydrogen chloride (HCl) is dissolved in water to make 4.5 L of solution. The task is to determine the pH of the resulting hydrochloric acid solution. The pH should be expressed numerically to two decimal places. - Input field for pH calculation is provided with a submit button. **Part B:** - A sample of 0.35 g of sodium hydroxide (NaOH) pellets is dissolved in water to make 8.0 L of solution. The task is to determine the pH of this solution. The pH should be expressed numerically to two decimal places. - Input field for pH calculation is also provided with a submit button.
