Although acids are molecular compounds they act like ionic compound in water because they separate into a cation and an anion. The cation is always H +, and the anion depends on the particular acid. An acid is named for the characteristic anion it produces. Below is a flow chart illustrating the rules for naming acids. If the anion ends in… -ide add the hydro- prefix replace –ide with –ic and add the word acid Example: HCl inonizes into H+ & ClCl- = chloride Hydrochloric Acid -ate -ite replace –ate with –ic and add the word acid replace –ite with -ous and add the word acid DO NOT ADD THE PREFIX HYDRO- DO NOT ADD THE PREFIX HYDRO- Example: HC2H3O2 ionizes into H+ & C2H3O2C2H3O2- = acetate Acetic Acid Example: HNO2 ionizes into H+ & NO2NO2- = Nitrite Nitrous Acid Anions - 1 Acetate…….….C2H3O2 Hydroxide…….…..OHAluminate……..AlO2Iodate……………...IO3Amide………….NH2 Iodite…………......IO2Astatate…….......AtO3 Nitrate…………….NO3Azide…………….N3Bicarbonate…….HCO3- Nitrite…………...NO2Perbromate…….…BrO4Bismuthate….....BiO3Perchlorate………..ClO4Bromate……….BrO3 Periodate…………..IO4Chlorate…….….ClO3 Permangnate….…MnO4Chlorite………...ClO2 Chromite….….….CrO2- Perrhennate…….....ReO4Thiocyanate………..SCNCyanate……….
