My daughter is studying in class 10th. She just asked me today to find the brief note for the baking soda since her phone data was over. I Googled the question and went through many answers. I wanted to understand the answer before I sent it to her. Trust me, I found unnecessary and very long unsolicited answer which I wasn’t able to understand properly then how my daughter could? Finally I found this answer in a very simple and accurate technique from your page. I guarantee this is the only answer which can be effortlessly understood and learnt by students. I have sent this to my daughter and she thanked me. I would like to appreciate to the writer who doing effort to provide such study material free of cost.
