Answer
analyte
Explanation
Analyte : Chemical species which is going to be estimated in any quantitative analysis
Titrant : Solution of known concentration of chemical species which is primarily used to estimate the analyte in an titration.
Solvent : Any liquid substance which is used to dissolve an compound
Solute : Any compound which is dissolved in an solvent.

What are some key features of titration analysis? Select all that apply: The amount of titrant added can be used to determine the amount of analyte originally present. The amount of analyte added can be used to determine the amount of titrant originally present. Titrations are only useful for acid-base reactions. They Titration analysis generally involves using an indicator to show the end point. What is the hybridization around the oxygen atom in CH,OH? Select the correct answer below: O...

The chart below has entries for several steps along the titration curve (which shows the pH as a function of the volume of NaOH solution added). To calculate the pH at each step, you must first understand what species are present and which chemical reactions are occurring, as that will dictate the method needed to calculate the pH. For each volume listed, Fill in the table with the major species (one or more) present in solution that could impact the...
