2 ACIDS form when hydrogen compounds dissolve in water The subscript (aq) indicates aqueous which means dissolved in water Acid molecules ionize in water to produce hydrogen ions (H + ) Examples of acids HCl(aq) H 2 SO 4 (aq) H 2 SO 3 (aq)

3 A BASE is an ionic compound that contains the hydroxide ion OH - eg. sodium hydroxide NaOH calcium hydroxide Ca(OH) 2 Ionic compounds that are neither acid nor base are referred to as SALTS.

5 Physical Properties Acids Tastes sour (lemons) Reacts with metals and carbonates Bases Tastes bitter (soap) Feels slippery ph < 7 ph > 7 Conducts electricity Conducts electricity

6 ph scale

7

8 There are three patterns for naming acids. The ionic name is needed to write acid names and formulas. Ionic name Acid name 1) hydrogen ide hydro ic acid 2) hydrogen ate ic acid 3) hydrogen ite ous acid

9 To Write Acid Names 1) Write the ionic name for the hydrogen compound. 2) Apply the correct rule for the acid name.

10 Examples: HCl (aq) hydrogen chloride hydrochloric acid HClO 3(aq) hydrogen chlorate chloric acid HClO 2(aq) hydrogen chlorite chlorous acid

11

12 To Write Acid Formulas 1) Use the correct rule to write the ionic name. 2) Use ion charges to write the formula. eg. chromic acid hydrogen chromate H + & CrO 4 2- H 2 CrO 4(aq)

13 Writing Acid Formulas eg. hydrofluoric acid hydrogen fluoride H + F - HF (aq)

17 Law of Conservation of Mass Balancing Chemical Reactions Types of Chemical Reactions Simple Composition Simple Decomposition Single Replacement Double Replacement Hydrocarbon Combustion Neutralization Predicting Reaction Types

18 lead nitrate and potassium iodide in the video

19 Mass CANNOT be created nor destroyed. As applied to a chemical reaction, the MASS of the REACTANTS EQUALS the MASS of the PRODUCTS

20

21 Balanced chemical equations are a means of representing the process in a chemical reaction, whereby REACTANTS form PRODUCTS, as per the Law of Conservation of Mass. REACTANTS: PRODUCTS: ARROW: COEFFICIENTS: EXAMPLE: STARTING MATERIALS NEW MATERIALS Goes to Form or Yields # in front of FORMULA Iron + oxygen iron (III) oxide 4 Fe (s) + 3 O 2(g) 2 Fe 2 O 3(s)

22 1) Make a LIST of atoms for REACTANTS and PRODUCTS. 2) Count up the NUMBER OF ATOMS on each side. 3) ADD coefficients in front of the chemical formulae until you have equal numbers on each side. POINTS TO REMEMBER: i. Start with atom that appears in only 1 formula on each side first. ii. Lowest Common Multiple Rule for coefficients iii. Keep polyatomic ions together.

23 Balance the following chemical reactions: Mg (s) + O 2(g) MgO (s) CH 4(g) + O 2(g) CO 2(g) + H 2 O (g)

24 Mg (s) + HNO 3(aq) H 2(g) + Mg(NO 3 ) 2(aq) H 2 SO 4(aq) + NaOH (aq) Na 2 SO 4(aq) + H 2 O (l)

32 SIMPLE COMPOSITION/SYNTHESIS (SC): ELEMENT + ELEMENT COMPOUND SIMPLE DECOMPOSITION (SD): COMPOUND ELEMENT + ELEMENT SINGLE REPLACEMENT (SR): ELEMENT + COMPOUND ELEMENT + COMPOUND DOUBLE REPLACEMENT (DR): COMPOUND + COMPOUND COMPOUND + COMPOUND HYDROCARBON COMBUSTION (HC): C x H y + O 2 CO 2 + H 2 O NEUTRALIZATION: ACID + BASE SALT + WATER

33 When studying our chemical reactions, we will use the analogy of RELATIONSHIPS and DANCING!!! CATIONS will be FEMALES (remember, they re positive ions ) ANIONS will be MALES (remember, they re negative ions )

34 GENERAL EQUATION: Element + Element Compound ANALOGY: RELATIONSHIP Amy + Bob Amy-Bob A + B A-B

35 EXAMPLES: 4 Fe + 3 O 2 2 Fe 2 O 3 2 Na + Cl 2 2 NaCl

36 PREDICT THE PRODUCTS: Li + Cl 2 Mg + N 2

47 GENERAL EQUATION: NEW! Element + Compound Element NEW! + Compound ANALOGY: CHEATING!!! Amy-Bob + Charlie Amy-Charlie + Bob Why Amy, Why? A-B + C A-C + B

48 EXAMPLES: 1 K + 1 NaCl 1 Na + 1 KCl 1 Cu + 2 AgNO 3 2 Ag + 1 Cu(NO 3 ) 2

49 PREDICT THE PRODUCTS: ZnS + O 2 Br 2 + NaI

50

51 WHAT S WRONG WITH THE FOLLOWING EQUATION? 2 NaI + 1 Br 2 2 Na + 2 IBr There are 2 NEGATIVE IONS put together on the PRODUCT SIDE. IONIC COMPOUNDS are made up of a CATION and an ANION. CORRECT EQUATION: 2 NaI + 1 Br 2 2 NaBr + 1 I 2

52 GENERAL EQUATION: NEW! NEW! Compound + Compound Compound + Compound ANALOGY: Switching Partners Amy-Bob + Candice-Dave Amy-Dave + Candice-Bob A-B + C-D A-D + C-B

53 EXAMPLES: 2 NaCl + 1 MgS 1 Na 2 S + 1 MgCl 2 2 AgNO H 2 SO 4 1 Ag 2 SO HNO 3

54 PREDICT THE PRODUCTS: Al(NO 3 ) 3 + H 2 SO 4 Pb(NO 3 ) 2 + CaSO 4

55

56 WHAT S WRONG WITH THE FOLLOWING EQUATION? 1 Ca(OH) MgCl 2 1 CaMg + 2 ClOH There are 2 NEGATIVE IONS and 2 POSITIVE IONS put together on the PRODUCT SIDE. IONIC COMPOUNDS are made up of a CATION and an ANION. CORRECT EQUATION: 1 Ca(OH) MgCl 2 1 CaCl Mg(OH) 2

57 Do the 2 sheets on SINGLE REPLACEMENT and DOUBLE REPLACEMENT that FOLLOW in your booklet! Remember, CATIONS are always paired with ANIONS and be positive before being negative! Also, REMEMBER your H 2 O 2 F 2 Br 2 I 2 N 2 Cl 2 P 4 S 8

62 GENERAL EQUATION: C x H y + O 2 CO 2 + H 2 O FOR TRICKY BALANCING, TRY THIS: Divide the SUBSCRIPT of the H in C x H y by 2. If your answer is: EVEN ODD BALANCE using C-H-O Add a 2 coefficient to the CxHy and THEN BALANCE using C-H-O

63 PREDICT THE PRODUCTS: CH 4 + O 2 CO 2 + H 2 O C 2 H 6 + O 2 CO 2 + H 2 O C 5 H 12 + O 2 CO 2 + H 2 O

64 PREDICT THE PRODUCTS: CH 4 + O 2 CO 2 + H 2 O C 2 H 6 + O 2 CO 2 + H 2 O C 5 H 12 + O 2 CO 2 + H 2 O

65 GENERAL EQUATION: ACID + BASE SALT + WATER Also considered a DOUBLE REPLACEMENT REACTION

3/27/2015. So the question that arises is, how can you tell the difference between an ionic solution and a solution containing a molecular acid? A neat thing about chemistry is that there are exceptions to most rules. Previously, we learned that ionic compounds form electrolytic solutions but molecular compounds do not form electrolytic solutions.
