Maya, a student, performs a titration. She completes the following steps as part of her titration procedure. 1. She cleans and r
inses a burette with base solution. 2. She fills the burette with standardized base solution. 3. She adds a base from a burette to an acid. 4. She observes a color change in the Erlenmeyer flask. 5. She continues to add more base. Based on the above procedure, will she obtain accurate results? Yes, because the more base there is, the better the results will be. No, because she initially contaminated the burette with base. Yes, because she used a standardized base solution in the burette. No, because she did not stop adding base once the color changed.
Answer is: <span>No, because she did not stop adding base once the color changed. </span>The endpoint<span> is the point at which the indicator changes colour in a colourimetric </span>titration and that is point when titration must stop or results are going to be wrong, because t<span>he </span><span>equivalence point of titration is not measured right.</span>
Particulate movement and energy increases when a liquid is heated to its boiling point. Explanation: When a liquid is heated to its boiling point, the form of the liquid changes. ... The particles with cinematic energy begin to move more randomly. So we can say that the particle movement and the energy grow.
