Chemistry X | Acids, Bases and Salts | Importance of pH in Everyday Life
Importance of pH in Everyday Life Are plants and animals pH sensitive? Our body works within the pH range of 7.0 to 7.8. Living organisms can survive only in a narrow range of pH change. When pH of rain water is less than 5.6, it is called acid rain. When acid rain flows into the…

Chemistry X | Acids, Bases and Salts | HOW STRONG ARE ACID OR BASE SOLUTIONS?
HOW STRONG ARE ACID OR BASE SOLUTIONS? We know how acid-base indicators can be used to distinguish between an acid and a base. We have also learnt in the previous section about dilution and decrease in concentration of H+ or OH– ions in solutions. Can we quantitatively find the amount of these ions present in…
