Phenolphthalein indicator was added, and the solution in the flask was titrated with 0.215m naoh until the indicator just turned pink(ph=8-9). the exact value of naoh required was 22.75ml. calculate the concentration of hcl in the original 10.00 ml sample. can someone explain how to do it? ?

0489 M is the concentration of HCl in the original 10.00 mL sample.

Explanation:

To calculate the concentration of acid, we use the equation given by neutralization reaction:

where,

are the n-factor, molarity and volume of acid which is

are the n-factor, molarity and volume of base which is NaOH.

We are given:

0489 M is the concentration of HCl in the original 10.00 mL sample.

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.

explanation:

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
