AICE Chemistry | Chapter 11.4: Reactions with Water and Solubility Trends

Описание: This lecture covers Section 11.4: Reactions with Water. We will examine the behavior of Group 2 metals and their oxides in water, focusing specifically on the solubility of the resulting hydroxides.

In this video, we will cover:

Metals with Water:

-Magnesium: Reacts very slowly with cold water but vigorously with steam to form Magnesium Oxide (MgO) and a bright white glow.

-Ca, Sr, Ba: React with cold water to form hydroxides and hydrogen gas, with reactivity increasing down the group.

Oxides with Water: forming alkaline hydroxide solutions

Solubility Trends: The trend in solubility of Group 2 ionic compounds

Alkalinity Trend: As solubility increases, more hydroxide ions dissociate, leading to a higher pH (more strongly alkaline) solution as we move from Mg (pH ~10) to Ba (pH ~13-14).

This video is designed to align with the Cambridge AICE Chemistry (9701) curriculum and is based on the official course textbook and lecture materials.
