ACIDS BASES AND SALTS) ASSESSMENT TECHNIQUE: ART INTEGRATED PROJECT OBJECTIVES: To identify the organic acids present in a
number of substances we use in everyday life : eg: Tomato , apple, grapes, orange, curd etc.
[Make a video presentation for the activity that you are doing.]
Identify the pH values of samples of soil collected from different places.
Prepare a list of crops that can be grown in each area based on its pH value.
Talk with farmers ask them how they are dealing with the acidity and basicity of soil, and how well their crop grows.
Use Homemade litmus paper to test acidity and basicity of different substances used in daily life.
Comparative Analysis of the Properties of Acid-Base Indicator of Rose (Rosa setigera), purple cabbage and Hibiscus (Hibiscus rosa-sinensis) Flowers [Visual /Pictorial representation]

What volume of a 2.00 m stock solution of naoh is needed to prepare 150. ml of 0.40 m solution?

Complete the following reactions using word and balanced equations including states. dilute phosphoric acid is added with a calcium hydroxide solution.

Part b: study of equilibrium on solubility: mg(oh)2(s) ⇌ mg2+(aq) + 2 oh–(aq) cloudy clear (pink) 7. a. b. 8. a. b. 9. 10. 11. 12. when adding concentrated hydrochloric acid, how did the appearance of the equilibrium mixture change? the change in appearance indicated a shift in the point of equilibrium. in which direction did the equilibrium shift? (l) left (r) right explain your answer to question 7a. you should indicate which ion was added to or removed from the equilibrium mixture. when adding edta, how did the appearance of the equilibrium mixture change? the change in appearance indicated a shift in the point of equilibrium. in which direction did the equilibrium shift? (l) left (r) right explain your answer to question 8a. you should indicate which ion was added to or removed from the equilibrium mixture. upon heating in which direction is the equilibrium shifting? upon cooling in which direction is the equilibrium shifting? is the forward reaction a. endothermic explain your answers to questions 9, 10, and 11.
