Acids And Bases
In science, I learnt that acids are a group of chemical substances defined by their ability to donate hydrogen ions when dissolved in water. They are characterized by a sour taste and the ability to turn blue litmus paper red. On the pH scale, acids always have a value ranging from 0 to just under 7, with lower numbers meaning stronger acidity. Common everyday examples include citric acid in lemons and some type of acid in vinegar. When acids react with bases, they undergo a neutralization process that typically produces water and a salt. Bases are substances that accept hydrogen ions or release hydroxide in water. They are characterized by a bitter taste, a slippery feel, and the ability to turn red litmus paper blue. On the pH scale, bases range from above 7 to 14, and they react with acids to form water and salt through neutralization. Common examples include baking soda, soap, and bleach.
We did a test for hydrogen gas experiment where we mixed magnesium metal and hcl and once enough pressure had built up, bring the lit match to the mouth of the test tube and quickly uncover and the gas quickly comes out blowing out the match with a pop sound depending on the pressure that had built up.It was pretty easy with what we had to do even though my group just looked around, it was fine working on my own tho, it was fun and easy going.
In the future I think it would be cool to work more solo when doing experiments.
I think the most challenging thing about science is understanding what I am doing without getting help from my friends and classmates.
