🧪 SOLUBILITY RULES – DO YOU REALLY KNOW THEM?

Most students memorize solubility rules…
But only a few truly understand them.

Today’s challenge tests your grasp of one key concept in inorganic chemistry:

👉 Which sulfate is insoluble in water?
Remember:
All Group I salts are soluble.
All ammonium salts are soluble.
Most sulfates are soluble…
But there are important exceptions 👀
Can you spot the exception?
This is the kind of question that appears in:
✔ IGCSE Chemistry
✔ CBC Senior Secondary assessments
✔ Practical analysis (qualitative chemistry)
✔ Precipitation reaction questions

Mastering solubility rules makes: 🔬 Ionic equations easier
🔬 Precipitation reactions predictable
🔬 Qualitative analysis straightforward
🔬 Exams less intimidating
Drop your answer in the comments 👇
Let’s see who truly understands salt solubility!

Renewable resources are naturally replenished over time, making them sustainable for long-term use. Forests, when properly managed, can regenerate and continue supporting ecosystems and human needs—unlike non-renewable resources such as coal, phosphates, and metals which take millions of years to form.

During respiration, energy is released from the breakdown of glucose. This energy is captured and stored in the form of ATP (adenosine triphosphate).

ATP is known as the energy currency of the cell because it provides readily available energy for cellular activities such as:

Active transport

Muscle contraction

Synthesis of substances

Cell division and growth

📌 Remember: Respiration releases energy → energy is stored in ATP.

Biology Notes: Photosynthesis

Photosynthesis is the process by which green plants manufacture food (glucose) using carbon dioxide and water in the presence of light energy and chlorophyll.

Word equation:

Carbon dioxide + Water → Glucose + Oxygen
(in the presence of light and chlorophyll)

Key points

☀️ Light energy provides the energy needed for the process.

🌿 Chlorophyll absorbs light energy.

Carbon dioxide (CO₂) enters the leaves from the air.

Water (H₂O) is absorbed from the soil by the roots and transported to the leaves.

Glucose is produced as food and may be stored as starch.

Oxygen (O₂) is released into the atmosphere.

Correct answer: C. Photosynthesis ✅

Biology Notes: Plant Parts and Their Functions

Stem — supports and transports
The stem supports the plant and transports water, mineral salts, and manufactured food to different parts of the plant.

Root hairs — absorb water and mineral salts
Root hairs increase the surface area of the roots, enabling efficient absorption of water and mineral salts from the soil.

Leaves — make food
Leaves are the main site of photosynthesis, where plants use sunlight, carbon dioxide, and water to manufacture food.

Key point: Leaves make food through photosynthesis
