Today: QUICKLY… use your colored pencils and color the acid area red, and the base area blue. Label the hydrogen ion concentration
pH paper Gives a Qualitative reading
In this lab, you will use: Gives a Qualitative reading pH paper blue red Gives a Quantitative reading
SOLUTIONS. Solutions Solutions - homogeneous systems.
PH worksheet (#1). 1. What is the pH of a solution with a hydrogen ion concentration of 1.0 x M? pH = -log [H + ] = - log (1.0 x ) = 5.
Acid-Base Notes. Acid- Compound that forms hydrogen ions (H + ) when dissolved in water Base – compounds that forms hydroxide ion (OH - ) when dissolved.
MIXTURES AND SOLUTIONS. MIXTURE a combination of substances in which the individual components retain their own properties. a combination of substances.
Strength of Acids and Bases. What makes a strong acid or base? The strength of an acid or base is based on how many acid or base particles break down.
PH notes pH = % Hydrogen. Many compounds are soluble (can dissolve) in water. When an ionic compound dissolves in water, ionic bonds are broken. As a.
Acids, Bases, and Solutions A hydrogen ion (H + ) is an atom of hydrogen that has lost its electron. An acid is any substance that produces hydrogen ions.
Aqueous solutions & concepts of pH Chapter I. Ion Product constant - water A. Acids→ hydronium ions (H 3 O+) Bases → hydroxide ions (OH-) B.Self.
Hydrogen Ions and Acidity Chapter What is K w ? K w is the equilibrium constant for the self-ionization of water Water molecules are in constant.
UNIQUE PROPERTIES OF WATER: Water can break apart to form hydrogen ions (H+) and hydroxide ions (OH-). Water can break apart to form hydrogen ions (H+)
CHEMISTRY Unit 10 Notes: Acid & Base Stuff. (1) Acids Release H+ (hydrogen ions) when they dissociate in water. Common Characteristics: – pH = 0-6 – Indicator.
The pH scale. pH Measure of acidity of a solution 0 to 14 Water is neutral because of equal amounts of hydrogen and hydroxide ions. Acidic solution has.
Water Basics Polar: part of the molecule is slightly positive… other part slightly negative – Oxygen (-) – Hydrogen (+) Oxygen “hogs” hydrogen electrons.
PH Scale Standard: 5d-students know how to use the pH scale to characterize acid and base solutions.
Water and solutions Water – Polarity Oxygen holds more electrons making it have a negative charge- hydrogen sides has a positive charge Polar compund-
Water Basics Polar: part of a molecule is slightly positive, while another part is slightly negative Oxygen “hogs” electrons from hydrogen – 8 protons:
PH and pOH Ways to measure Acidity/Basicity What is pH? What is pOH?
Indicators and pH To learn about pH and how indicators show a substance to be an acid or a base. Objective:
pH: The negative of the common logarithm of the hydronium ion concentration [H 3 O + ] ◦ pH stands for the French words pouvoir hydrogene, meaning “hydrogen.
PH Relative concentration of H + ions in water HOH ↔ H + + OH - O HH
Bellringer What is an acid? What is a base? What are some properties of an acid? What are some properties of a base?
Acids and Bases. Properties of Acids: Properties of ACIDS: 1. tastes sour.
ACIDS AND BASES. ACIDS & BASES Acids are substances that produce hydrogen ion in solution. (H + (aq) ) Bases are substances that produce hydroxide ions.

DO NOW: What is pH a measure of?. The pH scale pH pH is the -log of the hydrogen ion concentration Mathematically it is represented by the equation:
Unit 11 Acids and Bases. ACIDS Any substance that generates a hydrogen ion (H + ) when dissolved in water The pH of an acid ranges from 0-6; 0 is the.
PH Chapter Vocabulary Word hydronium ion: H 3 O + hydroxide ion: OH -
The attraction between a hydrogen atom on one water molecule and the oxygen atom on another Hydrogen bond.
Chapter 8 Acids, Bases, and pH. The pH scale pH scale is labeled = neutral 0-7 = acids, 7-14 = bases “weak”, closer to 7 “strong”, closer to 0.
NOTES: 19.2 – Hydrogen Ions & Acidity (pH and pOH)
ACIDS AND BASES PH. THE PH SCALE IS USED TO MEASURE HOW ACIDIC OR BASIC A LIQUID IS. THE SCALE RANGES FROM CLOSE TO 0 – 14 ACIDS RANGE FROM 0 - JUST BELOW.
