Hello everyone, my name is Martina and I am a chemistry teacher. I am from Germany but have been living in this country for the past 10 years. I love teaching chemistry as it fascinates me how elements react with each other to form new substances. I also enjoy conducting experiments in the lab to demonstrate chemical reactions to my students. Today we are going to learn about the pH scale and its importance in various fields such as biology, medicine, and environmental science. So let's get started!
