Acids, Bases, and pH Honors Chapter 2 Pages Regular Chapter 2 Pages 42-43
Water Molecule a review just look and listen
Ions Ionic bonds forms when one or more electrons are transferred from one atom to another. See page 38 of both text Ions are positively and negatively charges atoms …..H + and OH -
pH potential of Hydrogen H hydrogen ion OH hydroxide
Acid A solution that contain higher concentrations of H+ ions than pure water and has a pH values below 7.
Base Or alkaline, is a solution that contains lower concentrations of the H+ ion than pure water and have values above 7.
Buffer Are weak acids or bases that can react with strong acids or bases to prevent sharp, sudden changes in pH. Cells use this to control pH in the body
We’ll do this later today or next time!
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.
Biomolecules. Acids, Bases, and pH The pH scale: Chemist devised a measurement system called the pH scale to indicate the concentration of H+ ions in.
CH. 2-2 IN CLASS NOTES PROPERTIES OF WATER. Water, Water Everywhere If you have ever seen a photograph of Earth from space, you know that much of the.
Two water molecules. one water molecule Hydrogen ion Hydroxide ion.
PH Scientists use something called the pH scale to measure how acidic or basic a liquid is The scale looks at the concentration of positively charged hydrogen.
Continuing into the world of acids and bases…. pH of a solution is the negative logarithm of the hydrogen ion concentration pH = -log [H + ] This.
NOTES 10 – Acids, Bases, & pH. Ion Review An ion is an atom that gains or loses electrons giving it an overall positive or negative charge An ion is an.
Occasionally, a hydrogen atom shared by two water molecules shifts from one molecule to the other. Occasionally, a hydrogen atom shared by two water molecules.
Chemistry of Life. Element A substance that cannot be broken down into simpler substances. Each element is identified by a one or two letter symbol. Ca.
Chapter 2, Section 2. Interactions of Atoms Compounds – Atoms of more than one type of element that have been chemically bonded together – Often have.
CH. 2 Chemistry of life Section 1 Nature of matter Atoms Atom- is the smallest unit of matter that cannot be broken down by chemical means. Atoms consist.
Acids, Bases, and pH. Acids and Bases Acids produce H + ions which react with water to form hydronium (H 3 O + ) ions Bases produce OH - ions.
Solutions and pH. What is a Mixture? A mixture is a material compound Mixtures are made of two or more elements or compounds that are physically mixed.
2-2 Class Review 1. What does pH stand for? A. Phosphorus hydrogen B. Power of Hydrogen C. Potassium Hydrogen D. Pure Hydrogen.
Chapter 6.1 Atoms & their interactions Units of Matter ….. l Atoms l Elements l Compounds & Molecules lClC, O, H, N, S lClCO 2, H 2 0, C 6 H
The pH scale. pH scale This scale is used to determine the concentrat’n of H + ions versus OH - ions Things that are neutral are pH 7, acids are below.
CHAPTER 9 CONCURRENT ENROLLMENT. ACIDS AND BASES WEAK ACIDS AND BASES ONLY A FEW IONS ARE FORMED DEFINITIONS –Arrhenius - Acid contains H + ions and Bases.
Physical Science Acids & Bases. Solutions and Suspensions A mixture of flour & water suspension Colloidal dispersion solution Suspension - the particles.
I.N. 31 LIVING THINGS: Properties of Water AndAcids/BasesHeadingsVocabulary Important Words.
CHEMISTRY in Biology. Composition of Matter Matter - Everything in universe is composed of matter Matter is anything that occupies space or has mass Mass.
pH: a mathematical measure of hydrogen ions and hydroxide groups in a solution.
Acids & Bases They are everywhere.. In your food In your house EVEN IN YOU!!!!!
Chemistry of Life. Small to large AtomsElementMoleculeMacromoleculeCellsTissuesOrgansOrganism.
Chapter 7Mr. Kennedy. What is a solution? Solution-well-mixed mixture containing a solvent and at least one solute that has the same properties throughout.
Section 2.2. What do you know about water? Unique Properties of Water: Most abundant compound in nearly all living things.
PH is the measurement of the concentration of H+ ions in a solution. (Or how acidic or basic a solution is.) 1. The pH scale has a range from 1 to 14.
pH: a measure of the acidity or basicity of an aqueous solution The measure of hydrogen ions (these are positively charged)
1 The Nature of Molecules Chapter 3. 2 Water Chemistry Water consists of an oxygen atom bound to two hydrogen atoms by two single covalent bonds. – stable.
Chemistry Bellwork. Day 1 1. How do you know how many electrons an atom has? 1. How do you know how many electrons an atom has? 2. How do you know how.
Acids and Bases. Ionization of Water H 2 O + H 2 O H 3 O + + OH - K w = [H 3 O + ][OH - ] = 1.0
