Hydroiodic acid often is used to disinfect and sanitize medical tools and products. In an experiment, 5.0 mL of 0.75 mol/L HI(aq) is mixed with 20.0 mL of distilled water. If 1.0 mL of the diluted solution from #20 is added to 9.0 mL of distilled water, you should be able to predict the pH based on the trend you see and without doing any calculations. This is because every time the hydronium concentration increases or decreases by a factor of 10, the pH goes up one full unit since the solution becomes more or less acidic. 2)Hydrochloric acid is used for removing rust from iron or steel before it is processed for other uses. 5.18 g of HCl(g) is dissolved in water to make a 217 mL solution. Calculate the pH of the resulting solution. Record only your final answer with the correct number of significant digits.
