imagine that you go into the lab and perform a titration. you measure 40 ml of your analyte and add it to an erlenmeyer flask. t
o this you add three drops of an indicator solution that will change color from clear to blue. into your burette you add 50 ml of a 1.8 m standard titrant solution that reacts with your analyte in a 1:1 mole ratio. you do the titration and find that after you have added 26 ml of standard, the solution in your erlenmeyer flask turns blue. what is the original concentration of your analyte solution?
The Molar concentration of your analyte solution is 1.17 m
<h3>What is titration reaction?</h3>
Titration is a chemical analysis procedure that determines the amount of a sample's ingredient by adding a precisely known amount of another substance to the measured sample, with which the desired constituent reacts in a specific, known proportion.
Make use of the titration formula.
The formula is molarity (M) of the acid x volume (V) of the acid = molarity (M) of the base x volume (V) of the base.
if the titrant and analyte have a 1:1 mole ratio. (Molarity is a measure of a solution's concentration represented as the number of moles of solute per litre of solution.)
26 x 1.8 = 40 x M
M = 26 x1.8 /40
M = 1.17
The Molar concentration of your analyte solution is 1.17 m
The answer is (3). The reaction that can occur at the anode is oxidation reaction which will lose electrons. So (1) and (2) are not correct. For (4) Fe3+ can not lose electrons again.
Saturated fats are when fatty acid contains carbon that are connected by a single bond. Unsaturated fats are when one or more carbons form a double bond with another carbon.
