QUES TION 4 The pH value is an expression of the molarity of H30 ions in solution. This concentration has strong impact on chemical reactions. The molarity is very small value, and therefore awkward to use. The pH scale simplifies this concentration making communication easier and faster. Demonstrate the relationship between pH and H30 molarity, using the formula, pH = -log(H30) where ) indicates concentration in molarity of a substance. What is the pH of a solution, having the H30* concentration of 0.00014 M?
When carbon dioxide gas dissolves in water, it reacts with the water to form carbonic acid. This is why soft drinks have a low pH, and soda water is often recommended as a mild cleaning agent. It is also why there is concern that rising levels of atmospheric carbon dioxide may cause the Earth's oceans to become more acidic. Here is the reaction between carbon dioxide gas and water: H₂O(1)+CO₂(g) → H₂CO3(aq) Suppose an engineer decides to study the rate of this reaction. He prepares four reaction vessels with 131.4 g of water and 31.5 g of carbon dioxide gas each. The volume and temperature of each vessel is shown in the table below. Arrange the reaction vessels in decreasing order of initial rate of reaction. In other words, select a "1" next to the vessel in which the engineer can reasonably expect the initial rate of reaction to be highest, a "2" next to the vessel in which the initial rate of reaction would be next highest, and so on. vessel volume temperature A B C D 20L 4.0 L 2.0…
