I know this is a extremely dangerous experiment to actuly try (as in drinking it) so I wont attempt that, but im thinking theoretical>>
Here is my science Lab write up, tell me what you think about it:
PART ONE A (Universal Control)
I. Title: TUMS©… or Drano©?
II. Purpose: The purpose of PART ONE A is to create a universal control (for PART ONE B and PART TWO) of Na(OH) + HCl that is proven to create, if the amount of each of the reactants is equivalent at the correct mole ratios, H2O + NaCl. Another purpose of this universal control is to measure the pH of all substances created and used in the experiment.
III. Background Research:
i. Na(OH) + HCl is proven to make NaCl + H2O when the acid/base neutralization of the substance occurs.
ii. According to many different sources of Internet websites, Drano© is not pure Na(OH) and may contain aluminum chips, and is therefore the neutralization may not be as effective as the pure Na(OH) tested in ‘Part One A’
V. Materials:
i. 100mL of HCl (12 molar)
ii. 100mL of Na(OH)
iii. Graduated cylinders or other measurement tools
iv. Protective gear (Eyeglasses/gloves)
v. pH indicator paper
VI. Methods:
1a. Measure 100mL of HCl in a graduated cylinder
2a. Measure pH level of the 100mL of HCl
1b. Measure 100mL of Na(OH) in a graduated cylinder
2b. Measure pH level of the 100mL of Na(OH)
3. Mix the Na(OH) {20mL at a time} with HCl {full 100mL}
4.Measure the pH {of each 20mL added to the solution}
5. Wait for approximately five minutes to measure pH level IF no immediate change in pH level.
PART ONE B (Base Control)
II. Purpose: The purpose of PART ONE B, is to generate a control for PART TWO of my experiment, and to see if Drano©, hypothetically Na(OH), would actually react with HCl to form a solution of NaCl + H2O and to test the pH of that solution. {HCl + Na(OH) à H2O + NaCl | presuming that Na(OH) is the equivalent to Drano©}
IV. Hypothesis: If Na(OH) + HCl à H2O + NaCl and Drano© is the equivalent to Na(OH) then the reaction of Drano© + HCl à H2O + NaCl will be accurate. Also the pH of the solution will average approximately seven.
V. Materials:
i. 100mL of HCl
ii. 100mL of Drano©
iii. Graduated cylinders or other measurement tools
iv. Protective gear (Eyeglasses/gloves)
v. pH indicator paper
VI. Methods:
1a. Measure 100mL of Drano© in a graduated cylinder
1b.Measure pH level of the 100mL of Drano©
2. Measure 100mL of HCl in a graduated cylinder
3. Mix the Drano© {20mL} with HCl {full 100mL}
4.Measure the pH {of each 20mL added to the solution}
5. Wait for approximately five minutes to measure pH level IF no immediate change in pH level.
6. Repeat steps: 1a, 2, 3, 4, and 5, until all 100mL have been added to HCl, or the pH level of the solution is approximately seven.
VII. Results:
VIII. Conclusion and Discussion:
IX. New Questions:
PART TWO
II. Purpose: The purpose of PART TWO of TUMS© or Drano© is to test how much Drano© is necessary to add to 100mL HCl to result as the equivalent of one TUM© by measuring the pH of a solution: 1(TUM) + HCl in comparison to Drano© + HCl (tested in PART ONE B).
III. Background Research: In school we were taught that TUMS© help stomachaches by neutralizing the stomach acids a slight amount.
IV. Hypothesis: If Drano© + HCl is equivalent to Na(OH) + HCl and Na(OH) + HCl à H2O + NaCl then 1(TUM) + HCl will be equivalent to a certain amount of Drano© (in mL) [needed which will be found in the course of the experiment] + HCl.
V. Materials
i. 100mL of HCl
ii. One TUM
iii. Graduated cylinders or other measurement tools
iv. Protective gear
v. pH indicator paper
vi. 50mL or more of Drano©
VI. Methods:
i. Measure pH of 100mL HCl
ii. Grind the TUM into powder
iii. Mix TUM powder with 100mL HCl
iv. Wait approximately three minutes to measure pH level IF no immediate change in pH level.
v. Measure another batch of 100mL HCl
vi. Add 5mL at a time of Drano© until the pH of the solution is equivalent to the TUM + HCl solution
