    Chemistry IA Help!!

    hey, so I recently started brainstorming on what I can do for my chemistry IA. I am doing HL chemistry and I am going into the final year of IB. I have somewhat of a basis on what I want to do. I want to do titration, having the acid be hydrochloric acid and using various basic solutions. For the basic solutions, I want to create solutions from some antacids and compare how each antacid works by seeing how much of each is needed for the pH of the acid to reach and maintain a neutral pH. I'm not sure if this is going to work because this idea is still in the works. Any ideas or tips on how I can improve??
  3. Hi, I need help in finding a topic for my chemistry extended essay. I have already had some ideas such as doing an acid base titration. Maybe use honey as the acid or something. Or investigating the levels of acidity in different fruits and how they could be able to neutralise a specific base. Or maybe using vinegar. But that's all I have. I am not asking for a topic (because that would be cheating), but I would like to have some help in getting me on the right track to finding a suitable topic. Thanks.

    EE Chemistry HL research question

    Hello, IB-people. I'm taking Chemistry HL, my plan is to write an EE about Acids and Bases. I have a list of good sources but what bugs me most is what I should research. So what do you think would make a good research question, my friends?

    Acid/Base reaction chemistry sl

    Hi what will happen in this reaction 2 NaOH + H2SO4 → Na2SO4 + 2 H2O when I increase the concentration of one of the reactants. They form salt and water will a pH of 7. But if I increase the concentration of one of the reactants? will it effect the pH?
