1. At a certain temperature, the pH of a neutral solution is 7.67. What is the value of Kw at that temperature?
2. What is the pH of a neutral solution at a temperature where Kw=8.0×10-14?
3. Calculate the pH of a solution prepared by dissolving 0.40 g of BaO in enough water to make 0.600 L of solution.
4. The temperature for each solution is carried out at approximately 297 K where Kw=1.00×10-14 0.50 g of hydrogen chloride (HCl) is dissolved in water to make 6.0 L of solution. What is the pH of the resulting hydrochloric acid solution?
Express the pH numerically to two decimal places.
0.75 g of sodium hydroxide (NaOH) pellets are dissolved in water to make 5.5 L of solution. What is the pH of this solution?
Express the pH numerically to two decimal places.
