'Base reactions' presentation slideshows

Acids & Bases. They are everywhere.. In your food In your house EVEN IN YOU!!!!!. What is an acid?. An acid is a solution that has an excess of H+ ions. It comes from the Latin word acidus that means "sharp" or "sour". The more H + ions, the more acidic the solution. Properties of an Acid.

Chapter 4: Aqueous Stoichiometry. Properties of Aqueous Solutions. Terms to know Solutions (Solvent and Solute) Dissociation of Ionic Compounds Strong and Weak electrolytes. Why is Water the Common Solvent?. Water is very polar The oxygen atom gains a slight excess negative charge ( δ -)

Chapter 9 Alkynes. 9.1 Sources of Alkynes. +. H 2. +. H 2. HC. CH. CH 2. H 2 C. Acetylene. Industrial preparation of acetylene is by dehydrogenation of ethylene. 800°C. CH 2. H 2 C. CH 3 CH 3. 1150°C. cost of energy makes acetylene a more

Methods: Fluorescence. Biochemistry 4000 Dr. Ute Kothe. Remember: Absorbance. Absorbance of monochromatic light reduces the intensity (I) Measured relatively to original intensity (I 0 )

Unit 09a : Advanced Hydrogeology. Chemical Reactions. Chemical Reactions. A wide variety of chemical reactions can take place between gases, solutes and solids in groundwater systems: Acid-base Solution-precipitation Complexation. Redox Hydrolysis Isotopic processes.

Chapter 21 “Neutralization”. Section 21.1 Neutralization Reactions. OBJECTIVES: Explain how acid-base titration is used to calculate the concentration of an acid or a base. Section 21.1 Neutralization Reactions. OBJECTIVES: Explain the concept of equivalence in neutralization reactions.

Types of Chemical Reactions. Dissolution reactions Precipitation reactions Acid-base reactions Redox reactions Complexation reactions. Read Chapter 5 (Introduction to Reactions in Aqueous Solutions). Dissolution Reactions Solute Dissolves in solvent to produce a solution

Reactions in solution. A subset of chemical reactions. Learning objectives. Define solution and its components Distinguish among strong, weak and non-electrolyte Identify strong acids and strong bases Apply solubility rules to prediction of precipitate formation

Section 7-4 . Acids and Bases in Solution. Acids in Solution. An acid produces a hydrogen ion (H+) when dissolved in water. Actually just a nakey proton. Polyatomic Ions. Polyatomic ions are groups of atoms with a charge: Always covalently bonded molecules (non-metals) Examples:

Acid-Base Reactions. Definitions . Strong Acids HCl HBr HI HNO 3 HClO 4 H 2 SO 4. Acid: a species that supplies H + ions to water Strong acid: an acid that completely ionizes in water forming an H + ion and an anion

5 Oct. 2010. Objective: SWBAT describe properties of an aqueous solution, and write an equation for a precipitation reaction. Do now: What is an electrolyte? Describe why it exhibits the properties of an electrolyte. Agenda. Do now Aqueous solutions notes

Acids & Bases. They are everywhere.. In your food In your house EVEN IN YOU!!!!!. What is an acid?. An acid is a solution that has an excess of H + ions. It comes from the Latin word acidus that means "sharp" or "sour". The more H + ions, the more acidic the solution.

Chapter 4 Notes - Types of Chemical Reactions and Solution Chemistry. Water, the Common Solvent. A. Structure of water 1. Oxygen's electronegativity is high (3.5) and hydrogen's is low (2.1) 2. Water is a bent molecule 3. Water is a polar molecule

Topic 2. Solution Stoichiometry and Chemical Reactions. Parts of Solutions. Solution- homogeneous mixture. Solute- what gets dissolved. Solvent- what does the dissolving. Soluble- Can be dissolved. Miscible- liquids dissolve in each other. Water, the Common Solvent.

Which is the stronger acid?. HNO 2 HNO 3. Which is the stronger base?. NO 2 - NO 3 -. Acid-Base Reactions. strong acid + strong base strong acid + weak base weak acid + strong base weak acid + weak base. Extent of Weak Acid-Weak Base Reactions. Extent of Weak Acid-Weak Base Reactions.

Acids and Bases. Properties of Acids. Produce H + (hydrogen) ions in water Taste sour Corrode metals React with bases to form a salt and water pH is less than 7 Turns blue litmus paper to red “Blue to Red A-CID”. Examples of Common Acids. Acetic acid (vinegar)

Acid-Base Reactions. Ch 17.6. What kind of reactions are possible?. There are 4 types: Strong Acid/ Strong Base Strong Acid/ Weak Base Weak Acid/ Strong Base Weak Acid/ Weak Base = no fun. Strong Acid and Strong Base . It is easy since it is 100% Ionized

Chapter 18 Acids, Bases & Salts. Properties of Acids. Homogeneous mixture Sour, sharp, and tart taste Conduct electricity – weak to strong electrolyte React with metals and produces hydrogen gas produce hydrogen ion (H + ) when dissolved in water

Week 2, Lesson 1. Chapter 4 – Analysing Acids and Bases. Acid Base Chemistry Revisited. Acids are proton donors. Bases are proton acceptors. Acid-base reactions involve the transfer of a proton from an acid to a base. Strong and Weak. Strong Acid: ionises almost completely in water.
