Use the References to access important values if needed for this question. Classify each of the following as a strong acid or a weak acid. Indicate how each should be written in aqueous solution. For example, should chlorous acid be represented as HClO2 or as H++ ClO2? phosphoric acid In solution, this acid should be written as hydrochloric acid In solution, this acid should be written as acetic acid- In solution, this acid should be written as

Write the chemical formual of acid: Cl-(aq0+HS04-(aq)  HCI(AQ+SO42-(aq)

Strong acids and strong bases ionize 100% in aqueous solution. HCl is a strong acid. In solution we write it as H"(aq) + Cl (aq). - HF is a weak acid. In solution we write it as HF(aq). - KOH is a strong base. In solution we write it as K*(aq) + OH (aq). - NH3 is a weak base. In solution we write it as NH3(aq). Exception: Since Ca(OH), is only slightly soluble we write it as Ca(OH)2(s). Below is a list of the 6 strong acids and 6 strong bases you should know. All other acids and bases are considered weak. Strong Bases LIOH, NaOH, КОН Strong Acids HCІ, HBr, HI HNO3 Ca(OH)2 (slightly soluble) HCIO4 Ba(OH)2 H2SO4 Sr(ОН)2

Which of the following chemical formulas corresponds to a base? HCl; KOH; H2SO4; HNO3

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 152.7 g of water and 34.3 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 8.0 L 1.0 L…
