Web275 views 1 year ago. This is a video introducing and revising the the concept of back titration. We work through a sample question to show the steps involved in back titration. WebTitration is a method commonly used in chemistry to figure out the amount of a chemical in a solution. This chemical is called the titrand. To figure out the amount of titrand in the solution, a known amount of a different chemical is added to the titrand's solution; this chemical— called the titrant, or titrating solution —reacts with the titrand. cannot find namespace xxx

WebBack titration (BT) can be used as a time-saving alternative for measuring BN. The titration technique depends on the indication of the endpoint to determine the concentration of the analyte (in this case, the amount of basic constituents) within a sample. WebFirst, calculate the number of moles of strong base required to reach the equivalence point of the titration. Then, using the mole ratio from the balanced neutralization equation, convert from moles of strong base to moles of acid. Finally, divide the number of moles of acid by the given volume of the acid solution to find the concentration.
