solute solvent substance being dissolved substance in which solute is dissolved “VATER”
H 2 O breaks up naturally H+ & OH- H H O
OXYGEN IS AN ELECTRON HOG
H 2 O breaks up naturally H+ & OH- H H O H H O + - & hydronium ion hydroxide ions
Solutions solute solvent ACIDSBASES ACIDS & BASES = measure the amount of hydronium ions (H + ) or hydroxide ions (OH - ) dissolved in a solution

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.
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.
Indicators and pH To learn about pH and how indicators show a substance to be an acid or a base. Objective:
Acids and Bases. Ionization of Water H 2 O + H 2 O H 3 O + + OH - K w = [H 3 O + ][OH - ] = 1.0
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.
pH: a mathematical measure of hydrogen ions and hydroxide groups in a solution.
Ch 11 Acids & Bases Test Review. 1.Color Change; Universal indicator- yellow, orange and red Blue Litmus paper turns red 2.) Sour taste and conducts.
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.
PH and pOH By: Sam F., Sam D., Rochani, Evan, Will, Sherry, Mariana.
Acids and Bases. Acids Acid comes from the Latin word Acidus meaning sour. Most common components of acid is a donatable proton or hydrogen ion (H + ).
pHpH pH scale- measure of H + ions (acidity); “power of hydrogen” H + = hydronium ion OH- = hydroxide ion #10.
Supplemental Information Lewis Dot Diagrams and Acids & Bases.
Intro to Acids & Bases. Ions in Solution ____________ – contain more H + than OH - ____________ – contain more OH - than H + ____________ – contain equal.
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.
Intro to Acids & Bases General Properties Indicators Neutralization Reactions.
Acids and Bases pH Calculations pH scale. pH Scale Created to express acidity as a more simple number than molarity. pH stands for “power” of the hydrogen.
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.
PH and concentration. HIGHER GRADE CHEMISTRY CALCULATIONS pH and Concentration pH is related to the concentration of hydrogen ions. e.g [H + (aq)] = 1.
Acids & Bases By Robert McGee. Our Goals for today To determine the difference between Acids & Bases Discuss the importance of studying Acids & Bases.
Warm Up A solution has a H+ ion concentration of 3.5 X M. a. What is the pH? b. What is the [OH - ]? c. What is the pOH? d. Would the litmus paper.
2-2 Class Review 1. What does pH stand for? A. Phosphorus hydrogen B. Power of Hydrogen C. Potassium Hydrogen D. Pure Hydrogen.
Aqueous Solutions and the Concept of pH Chapter 16.
Bell Ringer Which of the following aqueous solutions will cause litmus paper to turn red? A NaOH B NaCl C HCl D H 2 O pH Solution Added Litmus.
TEKS 10I: Define pH and use the hydrogen or hydroxide ion concentrations to calculate the pH of a solution. How is pH defined? The pH of a solution is.
PH. Acids Anything that produces H 3 O+ ions if dissolved in water Taste sour Turns blue litmus paper red When acids dissolve in water, it donates a H+ion.
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.
Sour to taste Turn litmus red Phenolphthalein stays colorless Electrolytes (conduct) React with some metals to form H 2 gas How do we recognize.
Mixtures & Solutions Biology. Mixtures Combination of substances where components retain their own properties Do not combine chemically Are the following.
