We have already learned about the physical properties of acids in this previous post. Let’s now focus on the chemical properties of acids (or how they react with other substances). 1. Reaction of Acids with Metals Acids react with metals to form a salt and hydrogen gas. Acids contain chemically bound hydrogen, which can be … Read more

In the previous post, we mentioned that one of the properties of acids is that they have sour tastes, while bases have bitter tastes. Using taste to classify substances as acids or bases is not an accurate method. It is not safe either due to the potential harm that acidic or basic substances can cause … Read more

Acids and bases are everywhere. When you squeeze a lemon to make lemonade, the juice is an acid. If your TV remote operates on battery power, the batteries contain acids. Acids flow through our bodies, aiding in food digestion and even facilitating muscle building. And what about bases? Well, if you washed your hands today, … Read more

In the previous section, we defined a compound as a pure substance made up of two or more elements chemically combined. Given the many ways in which elements can combine, the number of possible compounds is virtually limitless. But how do we name all these compounds? How can we know which elements constitute a compound? … Read more

In the previous section, we’ve learnt that a compound is a pure substance that is made up of two or more elements chemically combined. We also learnt in previous sections that that matter exists as pure substances and mixtures. So, what is the difference between a mixture and a compound? Well, the difference between a mixture … Read more

Key Takeaways: In our past posts on matter, we learnt that matter exists as pure substances and mixtures.  The pure substances can further be classified into elements and compounds. The elements comprise over 100 pure substances that are unique because they cannot be further broken down into simpler substances. All other pure substances (numbering in … Read more
