The reason for the fact that only a smallamount of indicator is used in the acid–base titration is to be explained. Concept introduction: Indicators are the substances that change the color of a solution with a change in pH. An acid-base indicator is a weak organic acid or base for which the ionized and un-ionized forms have different colors. Acid–base titration is a technique to analyze the unknown concentration of the acid or base with the help of the known concentration of the acid and base in reactions. Indicator is the substance thatis used to determine the end point of the acid-base titration . In the acid–base titration, organic substances are used as indicator. The equivalence point is also known as stoichiometric point. It is the point in a titration at which the amount of titrant added is enough for the complete neutralization of reaction.

You are trying to decide if there is a single reagent you can add that will make the following synthesis possible without any other major side products: xi 1. ☑ 2. H₂O хе i Draw the missing reagent X you think will make this synthesis work in the drawing area below. If there is no reagent that will make your desired product in good yield or without complications, just check the box under the drawing area and leave it blank. Click and drag to start drawing a structure. There is no reagent that will make this synthesis work without complications. : ☐ S ☐

Predict the major products of this organic reaction: H OH 1. LiAlH4 2. H₂O ? Note: be sure you use dash and wedge bonds when necessary, for example to distinguish between major products with different stereochemistry. Click and drag to start drawing a structure. G C टे

For each reaction below, decide if the first stable organic product that forms in solution will create a new C-C bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. NH2 CI MgCl ? Will the first product that forms in this reaction create a new CC bond? Yes No MgBr ? Will the first product that forms in this reaction create a new CC bond? Yes No G टे
