Before you perform your titration you calculate the expected volume of the titrant needed to reach the endpoint. Once you begin titrating you pass the expected endpoint without any color change. What is the first item you should check before proceeding further? a) If indicator has been added to the analyte b) If the correct concentration of titrant is being used c) If there is an air bubble in the burette tip d) If the stir bar is at a proper spin setting

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

Select ALL the steps you must take (but do not select any steps that are not essential) when you are preparing to do an acid-base titration (for example HCI titrated with NaOH). Select one or more: O a. Check if funnel is in top of burette, and if so, remove it. V b. Check for and, if necessary, remove air bubble from under tap. O c. Adjust liquid level in the burette to exactly 0.0 mL. O d. Remove burette from clamp to fill it with liquid. V e. Add indicator to solution in flask.
