Measuring the Concentration of a Dilute Solution of atomic number 11 Hydroxide
atomic number 11 hydrated oxide (NaOH) is a strong base and dissolves in water to form an alkali closure. The concentration of this solution end be determined by titrating it with a standard solution of hydrochloric acid (HCl). Titration, also known as mountaintric analysis, is a common laboratory method that is used to determine the inscrutable concentration of a known reactant (1). The solution of sodium hydroxide has a concentration of approximately 0.1mol dm -3. The formula for this test is as follows:
NaOH (aq)+ HCl (aq)?NaCl (aq)+H2O (aq)
The following will be necessary to perform the investigate:
Conical flask - For holding the sodium hydroxide
Pipette (10cm3) - For accurately measuring out the required volume of NaOH
Pipette pump
Burette (50cm3) - For dispensing the HCl into the conical flask
Burette Clamp
Clamp standpoint - For holding the burette steady
White Tile - For seeing the burnish change
Sink - For washing away used chemicals
-Chemical list:
Sodium hydroxide - (Also known as caustic soda) CAUTION - croupe cause chemical burns and is irritating if contact with sputter occurs.
Hydrochloric acid - Irritant, avoid contact with the skin.
Do not inhale, because it arouse cause coughing and inflammation of the throat. Avoid contact with the eyeball because it can cause blindness.
Methyl orangeness - Do not drink.
-Planning:
-Why am I using certain equipment?
Im using the 10cm3 pipettes to measuring stick the Sodium chloride and 50 cm3 burette to measure the hydrochloric acid because they give very accurate volumes, which is what we need in put to gain accurate results.
Im using a conical flask because they are better for this experiment than open flasks.
Im using the white tile because I can clearly see the colour change.
I plan on using 3 drops of methyl orange per 10cm3 of sodium hydroxide because it is a clear indicator, and the most commonly used in...If you want to get a full essay, order it on our website: Orderessay
