When doing a titration, you want to slowly add titrant until you reach a very specific point. You don't want to add any more than just the right amount because the question you want to solve is how much you have to add to reach that point! If you pass it, you can't go back and must start over.
If it like doing anything that must be done carefully -- if you do it too fast, you will mess it and not get the right result!

How would you explain the experimental results by adding quantum theory of light?
I would not even begin to plan an explanation until I knew what the experimental results are.
How do you standardize a titrant?
Use a well-known and well-characterized compound with a carefully measured concentration. If doing an acid-base titration always use a strong base or a strong acid, and not a weak one.See the Related Questions to the left for more information.
Why the weak acid cannot be used as titrant?
If you are titrating a base, using a weak acid as titrant would lead to the formation of a buffer as you added the weak acid. The weak acid would react with the base to form the salt of the weak acid + water, and this would buffer any changes in pH, thus making the titration meaningless.
How does concentration affect a titration?
It is easier to answer this by using examples. Let us suppose we have 4g of NaOH in 100 mls of waste water (4%). Titrating with 1M HCl would require 100ml of titrant. That would thus mean we would need 1000ml of 0.1M HCl titrant run from a buret which is extremely impractical. The concentrations thus affect volumes and thus titration flask sizes etc. It also would affect the time taken and the practicality.
Why would rising temperature speed up diffusion in a liquid?
Diffusion results from collisions between moving molecules. If the molecules are moving faster, they will collide more frequently. That will make them spread out, or diffuse, more quickly.

What would the Effect of adding salt to ice?
No, because the data does not show how quickly the ice would have melted without the salt.
Which results in a more valuable product -- adding or substracting protons from gold nuclei?
adding and subtracting protons from a gold atom would no longer make it gold.

How would the results of the starch hydrolysis change if glucose was added to the medium?
The starch is a different media. Therefore, by adding glucose to the medium it would throw off the results of the starch hydrolysis significantly.
How would adding air resistance change the results?
air resistance will increase the time for an object to fall to the ground
What does the term factor mean in science?
Something that helps to make up the final results of an experiment, and taking it away or adding stuff on to it would therefore change the final results of the experiment.

How many milliliters of 0.103 M HCl would be required to titrate 6.46 g KOH?
6.46g(KOH) / 56.108 g/mol(KOH) = 0.1151 mol(KOH) = 0.1151 mol(OH-) , which needs of the titrant the same amount of acid, so:0.1151 mol H+ = 0.1151 mol(HCl) / 0.103 mol(HCl)/L(titrant) = 1.118 L of this titrant ( 0.103 M HCl)= 1118 ml
What would the effects be if a person mixed hgh dhea and 5-htp Would it intensify the results more quickly?
Never mix drugs unless your doctor prescribes them in combination.
What would happen if there was a small hole that went straight through the entire planet?
In reality it would be quickly closed - with no real noticeable results. IF it were big enough, then you'd get earthquakes.
What is the manipulated variable in a titration?
The manipulated variable would be the volume of the titrant (the thing thats being added). This is the only part of a titration that is altered. The responding variable would be the pH of the solution.
