The arsenic in a 1.22-g sample of a pesticide was converted to AsO 4 3- by suitable chemical treatment. It was then titrated using Ag + to form Ag 3 AsO 4 as a precipitate. (b) Name Ag 3 AsO 4 by analogy to the corresponding compound containing phosphorus in place of arsenic.

Step 1: Identify the corresponding compound containing phosphorus in place of arsenic. In this case, the phosphorus compound would be Ag 3 PO 4 .. Step 2: Determine the name of the phosphorus compound. Ag 3 PO 4 is known as silver phosphate.. Step 3: Use the name of the phosphorus compound as a guide to name the arsenic compound. Replace 'phosphate' with 'arsenate' in the name of the phosphorus compound.. Step 4: The name of Ag 3 AsO 4 is therefore silver arsenate.

Hi everyone for this problem. It reads commercial bleach contains sodium hypochlorite which acts as the bleaching agent active ingredient, the concentration of sodium hypochlorite and bleaching solutions can be determined by redox titillation. Name this compound by analogy to sodium hypochlorite, a corresponding compound containing chlorine instead of bro. Mean? Okay, so we need to name this compound following the same analogy for sodium hypochlorite. Alright, so let's go ahead and write out our sodium hypochlorite a chemical formula and its name here is sodium hippo chloride. And we want to name this compound by the same analogy. So let's take a look at some key pieces here. So we see that we have the name sodium here. Alright, so that means this is going to stay the same. So we have sodium and another element that we have here is let's do it in a different color. We have the chlorine here. But over here we have bro mean. Alright, so we need to replace chlor with bro. Okay, so we have two other pieces of information. So we have this hypo here and we also have this right here. So the prefix hypo is used to indicate the very lowest oxidation state and the suffix ite is used for the ion that has the smallest number of oxygen atoms. So that's why we have hypo and right here. So essentially all we're replacing here is the chlor Oh or the chlor with bro. Okay, broom. So let's go ahead and do that. So by replacing it we're going to still keep the hypo and the ICT. So we have high bow and then we have bro might. Okay, so this is going to be the name of this compound following the same analogy. So it is going to be sodium hipAA bro. Might. Alright, so that's it for this problem. I hope this was helpful.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Nomenclature of Inorganic Compounds

Inorganic nomenclature involves naming compounds based on their chemical composition and structure. For example, the naming of metal salts often follows the pattern of naming the cation first followed by the anion. In this case, Ag3AsO4 can be named by drawing an analogy to similar compounds, such as those containing phosphorus, which helps in understanding the naming conventions.

Precipitation Reactions

Precipitation reactions occur when two soluble salts react to form an insoluble compound, known as a precipitate. In this scenario, the titration of AsO43- with Ag+ leads to the formation of Ag3AsO4, which precipitates out of solution. Understanding this concept is crucial for predicting the formation of solid products in chemical reactions.

Stoichiometry in Chemical Reactions

Stoichiometry involves the calculation of reactants and products in chemical reactions based on balanced equations. In the context of the question, knowing the stoichiometric ratios between Ag+ and AsO43- is essential for determining the amounts of each substance involved in the titration process. This concept is fundamental for quantifying the results of chemical analyses.
