PPT-Neutralisation

Starter What ions are found in acids What ions are found in alkalis What is the chemical formula for water give an example of a neutralisation reaction use a pH meter to measure pH observe the changes in pH during a neutralisation . Neutralisation reactions. Acids and bases . are opposite. One makes pH lower and the other makes pH higher. When acids and bases react they make pure water and a salt. Because pure water is pH 7 (neutral), this reaction is called a neutralisation reaction.. What . do you think happens . when an acid and an alkali are mixed? . ?. Write an idea in your book!. Stretch: People put vinegar on wasp stings.. Looking at our title and what we were learning last lesson, suggest why!?. QUESTION 1. Which of the following happens during . neutralisation. ?. I An acid loses its acidity.. II An alkali gains its alkalinity.. III The product is a neutral solution.. IV A salt and water are the only product of . tionof salts such as chlorides, sulphates, Neutralisation of Waste Water with Carbon Dioxide Swimming-pool water may notexceed a pH of 7.5; this is an environ- Industrial sectors that generatealkaline A West Midlands Health Technology Assessment Collaboration Report Authors: Janine Dretzke Fujian Song Correspondence to: Department of Public Health and Epidemiology University of Birmingham Hydrochloric acid + sodium hydroxide .  __________ + ___________.

(Flightpath D): Safely use universal indicator to classify a solution as acidic or alkaline. Describe the pH scale. Recall an example of an alkaline, neutral, basic, and acidic chemical. .. What is the pH scale?. What does it measure?. What range of values does it have?. How do you use the pH scale?. What can you use to measure pH?. Unit 4: Chemical Changes. L1: Acids and Alkalis.
