Common Acids & Bases: An inorganic acid is an acid that does not contain a carbon atom. An oxy-acid is an inorganic acid that contains oxygen. A carboxylic acid is an organic acid that contains carbon and oxygen. _____________________________________________________________________________________________ Hydroxides of alkali and alkaline earth metals contain elements from groups I and II respectively. Practice Skill: You will identify the three types of acids and give a scientific argument for your choices. You will also identify a base and give a scientific argument for your choice. A Scientific Argument includes: The Claim (an explanation or an answer to a phenomenon) Example: Phosphoric acid (H3PO4) is an inorganic oxy-acid. (the evidence supports the claim made based upon data and or observations) The Evidence Three pieces of evidence must be included. Example: It is a hydrogen containing compound. In an aqueous solution it will ionize into hydrogen ions (H+). It does not contain carbon but does contain oxygen. The Rationale (the reasoning that shows how the evidence supports the claim and why the evidence should count as support) Example: According to the formula H3PO4, Phosphoric acid is inorganic oxy-acid because it does not contain carbon but it does contain oxygen. In water it will release hydrogen ions; it can release three of them. Your turn: Explain what kind of an acid hydrochloric acid (HCl) is. The Claim:
