If you don't take responsibility for your tasks, it is unlikely others will step in. This is a reminder for you to take action now. ✨️

pH & pOH 🤯🔥

📌 pH is a measure of acidity

📌 pH shows the concentration of H⁺ (hydrogen ions).

📌 pOH is a measure of basicity

📌 pOH shows the concentration of OH⁻ (hydroxide ions).

📌 pH value of 0 - 6.9 is acidic

📌 pH value of 7 is neutral e.g. water

📌 pH value of 7.1 - 14 is alkaline or basic
