Honors Chem Ch 14 Pg 468 Acids Sour Give off H + (Arrhenius definition Pg 473) Know: formulas, names, strength, USES HFHClCH 3 COOH (vinegar) H 2 CO 3 HNO 3 H 3 PO 4 H 2 SO 4
Bases Pg 471 Bitter Slippery Cleaners Give off OH -- (Arrhenius definition) Know: formulas, names, strength, USES KOH NaOH NH 3 Ca(OH) 2 Mg(OH) 2
Both acids and bases are corrosive and conduct electricity Both are strong if they give off a lot of their ions, Pg 501**, Pg 512** Neutralization: Pg 489 #1 a-c Acid + Base salt + water
Chap 15 Pg 503 pH 0-6 = acid, strong = 0 (more H+ given off) 7 = neutral 8-14 = base, strong = 14 ( more OH- given off) Each # 10 x stronger than the next, like earthquakes, notice 10 -2, etc Pg 504 Why is rainwater pH 5.5?
Titration Pg 515 mixing acid + base until neutralized Pg 520 Samp F (cover Pg 521), Pg 521 Pract #2 Pg 521 Sect Rev 2,3 turn in?
Acids and Bases Chapter 19. Characteristics of Acids Acids –Sour tasting – vinegar, lemons –React with metals and produce H 2 (g) –React with metal carbonates.
Properties of acids n Taste Sour (kids, dont try this at home). n Conduct electricity. n Some are strong, some are weak electrolytes. n React with metals.
Acids and Bases. Properties of Acids They are corrosive pH range is 0 to 7, lower the pH, more acidic the acid Taste sour Turns litmus paper red Often.
What are the characteristics of Acids & Bases? ACIDS BASES TASTE SOUR BITTER TASTE SOUR BITTER FEEL STINGSON SKIN SLIPPERY,SMOOTH FEEL STINGSON SKIN SLIPPERY,SMOOTH.
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 + ).
Acids and Bases. Acids Acids are substances that release hydrogen ions, H +, in solution Acids are substances that release hydrogen ions, H +, in solution.
Acids and Bases. Arrhenius Theory Acids produce H + ions. Acids produce H + ions. Bases produce OH - ions. Bases produce OH - ions. HCl H + + Cl - NaOH.
pH: a mathematical measure of hydrogen ions and hydroxide groups in a solution.
1 Acids and Bases. 2 Properties of Acids þ Produce H + (as H 3 O + ) ions in water (the hydronium ion is a hydrogen ion attached to a water molecule)

Chapter 14 Acids, Bases, and pH. Comparing of Acids and Bases Observable properties – – Acids are sour – Bases are bitter and slippery to touch *** note.
LecturePLUS Timberlake1 8.2 & 8.3 – Acids, Bases & the pH Scale.
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.
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.
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.
pH Water Water is in equilibrium with its ions H 2 O(l) H + (aq) + OH - (aq) K w = [H + ][OH - ] K w = 1.0 x at 25°C In neutral solutions [H.
Chapter 19 Self-Ionization of Water and pH. Strong vs. Weak Strong: 100% dissociation of H + or OH – – Strong electrolytes (conduct electricity very well)
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.
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.
