What is Chemistry Experiments on Group 1 Reactivity about?

The document summarizes two chemistry experiments from a 2010 SPM exam. The first experiment investigates the reactivity of Group 1 elements (Li, Na, K) with water by measuring pH. Lithium produced the lowest pH. The second experiment examines the acidic properties of ethanoic acid by observing its reaction with magnesium in water and methylbenzene. Ethanoic acid reacted in water but not in methylbenzene, indicating it is a weak acid.
