Acid is titratd agains base...dis is simply bcos wen u pour 1 substance(liquid) against anoda...u will discover dat it is d substance alredy in d containa dat will splash out 2 give way 2 d incoming substance... Hence, if base is titrated gains acid... D titrator will b prone 2 danger as d acid may b corrosive wen it splashes... So i go wit B
While it's true that in general the acid is slowly added to the base during titration. In this specific case the reaction between the two substances is very vigorous and would be difficult to control if the diluted acid were added slowly to the strong base. The slow addition of the base allows for a more controlled reaction so in the titration setup involving sodium hydroxide (a strong base) and dilute hydrochloric acid (a strong acid), the base, which is sodium hydroxide would typically be placed in the burette. The burette is used to accurately measure and dispense the base solution into the conical flask, where the acid is present. it allows for a slow, precise addition of the sodium hydroxide, which prevents the reaction from getting out of control. By slowly adding the base from the burette to the acid in the conical flask, the reaction between the two can be monitored until the endpoint is reached. Therefore option C is correct.
what are you neutralizing, base or acid. I don't understand, is it not acid that you are neutralizing, hee
The acid (HCl) is placed in the conical flask (just like lemon juice in a cup)
The base (NaOH) is placed in the burette
We slowly add the base drop by drop from the burette into the acid while stirring.
We use an indicator (like phenolphthalein) to help us know when neutralization is complete.
Option C is the correct option

b z d krct option bcos after suckin ur base with d pipete to 20cm^3 or 25cm^3 mark u will nw pour d base 2 d conical flask 4 further step
base soln measure wit pipette & pour into a conical flask or beaker, while acid solution in a burrette clamp by retort stand. Now d titration commence by adding d acid soln into d conical flask & strt shaking until d colour change of an indicator (end point).
