Base and an alkali 4 of 21 However copper oxide and iron (iii) hydroxide are insoluble, meaning they're... Just bases 5 of 21 aq solutions of alkali's contain ___ OH- 6 of 21 What can we use to test the pH? Universal indicator or pH probe 7 of 21 Green shows a ___ solution Neutral 8 of 21 Red shows ___ solutions Acidic 9 of 21 Purple show ___ solutions Alkali 10 of 21 Acids have a pH of less then _ 7 11 of 21 While more then 7 is... Alkali 12 of 21 Solutions with pH of 7 are... Neutral 13 of 21 Acids produce __ while ___ produce OH- Acids = H+. Alkali = OH- 14 of 21 What do acids produce when they react with a metal?

Sulfate 17 of 21 Predict products: Hydrochloric acid + magnesium (remember: produces salt and hydrogen!) Magnesuim chloride + hydrogen 18 of 21 Magnesium is __ reactive then hydrogen more 19 of 21 This means mag. can easily d___ (replace) hydrogen in acids displace 20 of 21 Iron reacts slowler wityh Hydrogen then mag. why? Iron is closer (although still higher) to hydrogen on reactant series so will take longer to react as it's only slightly more reactive 21 of 21
