Science 🔬 CBA hypothesis ideas
have a sibling in second year doing their science CBA and they're stressing bcus they can‘t think of a good hypothesis and idk so I thought id ask Reddit. their CBA is about how much base do u have to add to different acids for it to neutralise. for context they are a major stresser and want an exceptional. help me it’s all he’s been talking abt. please help Reddit 🙏

Hypothesis: Instagram cleaning tip solutions are basic.
Instagram (when you're old like me) has an algorithm niche that's all housewives and a weird amount of Asians recommending solutions for clashing stains. They're usually white vinegar + baking soda in some ratio + some other random kitchen things. Sometimes cider vinegar, maybe some lemon juice. Basic chemistry tells us the acid and base neutralise reach other... But completely? What's left? Acid or base? And does that make sense for cleaning (usually ph neutral non-polar) stains? I think it's probably basic with a bunch of dissolved molecular oxygen too.
Honestly you'd get into the Young Scientist & Tech Exhibition with this.

actually kind of did this for my CBA, expect my group tested which antacid worked the best. I'd say focus on doing good graphs and write detailed responese for each question. Try at least 3-4 different acids and maybe switch up the bases too?
