Jak obliczyć pH? Skala pH, iloczyn jonowy wody i wzory — krok po kroku

How do you calculate pH and pOH? What is the pH scale and the ionic product of water? In this video, I explain everything you need to know about pH step by step—from the pH scale and the formulas (pH = −log[H⁺], pOH = −log[OH⁻]) to specific calculation examples. Perfect preparation for your chemistry final exam, test, or quiz. On the KaNaU channel, I explain chemistry step by step—no cramming, just understanding. 🔹 In this video, you'll learn: What the pH scale is and how to read it (0–14) What is the ionic product of water (Kw = 10⁻¹⁴) How to convert the concentration of H⁺ and OH⁻ ions to pH and pOH How to calculate pH when the concentration isn't a "round" power of ten The relationship pH + pOH = 14 ⏱ Table of contents: 00:00 – What is pH?
