please correct

Question 1 (1 point) Saved Certain acids are defined as weak acids which means that a small percentage of acid molecules ionize in water. True False Question 2 (1 point) Saved Strong acids, like Hydrochloric acid, completely ionize in water. True False Question 3 (1 point) Saved The equivalence point of titration is also known as the stoichiometric point or end point. True False Question 4 (1 point) Saved Phenolphthalein is a pH indicator which turns bright pink at a basic pH of 8.2 or

Answer 1

1) True > Reasonin Weak acid means it does not dissociates completly. Hence they dissolved in water then only all percentage of acid molecules water ionize in 2) True - Reason: من ( strong and like hydrochloric acid (HC) highly polar in nature due more electronegativity difference. They dissociates completly. Hence when they dissolved in water ionizes completly. 3) False → Reason: Equivalence point au Equivalence point and equivalent point are not same they are slightly differ from each. other. Equivalence point is the point where exact equivale ut moles of titrent added to the Atrand solution present in the flask. where as End point is the point where colour change l occur. Hence they are different. 4) True Reason:- Phenolphthalien in colourless in acidic medium and pink colour in basic medium. When pH of the solution reches to more than 8 it changes, it's colour from colourless to pink.
