Chapter 5 - How Much, How Fast & How Far?

Hey there, budding chemist! Let&#39;s unravel the world of acid-base equilibria in salt solutions with a sprinkle of fun. Grab your goggles and lab coat; we&#39;re diving in! 🥼🔍

<ul>
	<li>Salt: Think of a salt as a neutral kiddo made by getting together an acid and a base. It&#39;s like when Batman and Superman team up &ndash; they balance each other out!</li>
	<li>Hydrolysis: Salts + Water = Possible pH changes! This process is called hydrolysis.</li>
</ul>

Salts can arise from various acid-base match-ups:

<ul>
	<li>Strong Acid + Strong Base</li>
	<li>Strong Acid + Weak Base</li>
	<li>Weak Acid + Strong Base</li>
	<li>Weak Acid + Weak Base</li>
</ul>

<ul>
	<li>Example: Sodium chloride (NaCl)</li>
	<li>These are like rockstars! Neither ion (Na+ or Cl-) in the solution wants to mess with water. Result? Neutral pH (pH = 7).</li>
</ul>

<ul>
	<li>Example: Ammonium chloride (NH4Cl)</li>
	<li>Here, the cation (NH4+) is like a shy singer trying out for the school&#39;s musical. It interacts with water making the solution a bit acidic (pH &lt; 7).</li>
</ul>

<ul>
	<li>Example: Sodium ethanoate (CH3COONa)</li>
	<li>The anion (CH3COO-) is the star of the show! It makes the solution sway to a basic tune (pH &gt; 7).</li>
</ul>

<ul>
	<li>Example: Ammonium ethanoate (CH3COONH4)</li>
	<li>It&#39;s a dance between cations and anions! Depending on who&#39;s got stronger dance moves, the solution can be slightly acidic or basic. But often, they balance to a neutral pH.</li>
</ul>

<ul>
	<li>Hydrolysis is for the weak! - Only weak ions interact with water.</li>
	<li>The stronger wins! - If an acid&#39;s stronger, you&#39;ll get an acidic solution; if a base&#39;s stronger, it&#39;ll be basic.</li>
</ul>

Potassium Cyanide (KCN)

<ul>
	<li>KCN &rarr; K+ + CN-</li>
	<li>CN- undergoes hydrolysis: CN- + H2O ⇌ HCN + OH-</li>
	<li>Result? Basic solution!</li>
</ul>

... [Continue with other salts]

<ul>
	<li>Make a flowchart or scheme to visualize and understand interconnected calculations.</li>
	<li>Example: To hop from pH to [H+], think of it like hopping between different subway stops. You&#39;ll soon master the route without needing a map!</li>
</ul>

Remember, chemistry isn&#39;t just in the lab &ndash; it&#39;s everywhere. From baking soda volcanoes to the pH of your shampoo, the world is your chemistry playground! 🌍🔬🧪&nbsp;
