'Strong acid' diaporamas de présentation

Acids produce H + in solution, example: HCl Bases produce OH - in solution, example NaOH. What is an acid?. Acids are a group of chemicals. laboratory acids. everyday acids. Can you think of other examples of acids?. What is a weak acid?.

17 Acids and Bases. A group of chemical properties is related to acidity. According to these properties, a substance can be called an acid or a base . The word acid comes from Latin acere meaning sour. A base is an alkaline , which is derived from Arabic alqali .

Chapter 18. Acid-Base Equilibria. ACIDS & BASES Acids: - acids are sour tasting - Arrhenius acid: Any substance that when dissolved in water, increases the concentration of hydronium ion (H 3 O + ) - Bronsted-Lowry acid: A proton donor

Equilibrium. By: Blaise McNeese and Lauren James. What is Equilibrium?. Consider the reaction aA+bB <----> cC+ dD  Reactants A and B are forming products C and D. Now consider the reverse reaction of reactants C and D producing products A and B.
