THE QUESTION IS:
After someone tampered with the city water reservoir is the water safe to drink?
ACIDIC or BASIC?
General Objectives:
To discuss various solvents, their salvation power. Solvent, solute, solubility relation.
To discuss pH in terms where the pH= –log (H+)
Specific Objectives: IPC.08.B, C, E: Understand chemical reaction. Balance chemical reaction. IPC.09.A, D, E: Understand Physical and chemical properties of solvent and solution. IPC.09.A: Understand ionic concentration in solution. Make a Venn diagram of acid, base and salt. Vocabulary words and their definitions. Discuss acids, base and their uses. Discuss common bases. Hands on activity- how to distinguish acid and base (litmas reaction). Dissociation of acid /base solution, concept of hyronium (H3O+) and hydroxyl (OH-) ion. Why H+ ion cannot exist in solution? Students will be able to discuss strong acid and strong base. Hands on activity of electric conductance of strong acid and base solution. Introduce concept of pH , pOH, Kw of water. Discuss natural pH indicator.

BRUMBELLVILLE LAYOUT OF THE CITY COMING TO LIFE
THE ACTUAL MODEL OF BRUMBELLVILLE
• Liquid solutions would be either and an acid or base.
• Exception would be the solvent distilled water.
• Distilled water is just water.
• Ions in solution make something acidic or basic.
• In your body there are small compounds called “amino acids”. Those are acids.
• “citric acid”
A: When you dissolve it in water, a solution of baking soda will be a base. NaHCO3
• A: Vinegar, it’s an acid
• Water has a pH of 7, right at the middle, and it is neutral.
• Acids are found between 0 to 7.
• Bases are between 7 to 14.
• Most of the liquids you find every day have a ph near 7.
• Taste sour.• Corrode metals and
other substances• Burn your skin if
strongly concentrated• All acids no matter how
dilute, can damage your eyes and other areas of your body.
Household Acids
• Taste bitter
• Slippery
• Can be very dangerous if ingested or in contact with the skin Household Bases
Do you want to know how acidic or basic the
substances you commonly drink or deal with are? Well, why not try the
activity we have here?
Are you Ready?
Put your…
Goggles,
Gloves,
Apron,
And let’s start!!!
Introduction:•You can determine if a substance is an acid or base by using an indicator.
•An indicator will change colors when combined with an acid or a base.
•The color of the substance determines the pH.
Materials:
beakers lemon juice milk coffee
soda pH paper vinegar creamer
ammonia liquid cleaner antacid bleach
Procedure:
1. Obtain a beaker of each of the solutions and dip a one-inch piece of pH paper into one of the solutions.
2. Compare the color of the ph paper to the pH indicator.
3. Repeat steps 1 and 2 to each of all the other solutions.
4. Complete the Data table.
Data Table:Name of substance` pH Acidic or
BasicLemon juice

Coffee

Liquid cleaner
bleach
If vinegar is entered into the city, can the water still be consumed
by humans?
