1. Make Observe an event. State only what we can
or .
2. Ask
Ask a question that helps us find out and the event happened. We must be
able to answer the question with , or . We may need to our question several times before it is.
3. Construct a
State the answer we think we’ll get when we ask
our question. This is called a
. It’s based on our best
understanding of the event.
4. Test the hypothesis with an

Test whether the hypothesis is .
During the investigation, we collect that
answers the testable question we asked.

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. (l) left (r) right (l) left (r) right b. exothermic

Match the mixture with the substance// i really need on this guys (it’s a pic btw)

An observation that requires measurement is called quantitative observable or qualitative
