Kisline in baze so snovi, ki jih srečaš vsak dan... Show more






Kisline so snovi s kislim okusom, kot je limona ali jogurt. Močne kisline so jedke - to pomeni, da lahko poškodujejo kovine ali tvojo kožo, zato nikoli ne smeš poskušati neznanih snovi!
Baze (ali lugi) so na otip spolzke in milnate, kot milo. Imajo grenak okus in so prav tako lahko jedke kot kisline. Soda bikarbona je primer šibkejše baze, ki jo uporabljamo za peko.
Indikatorji so posebne snovi, ki nam s spremembo barve povedo, ali je neka raztopina kisla ali bazična. Delujejo kot detektivi za kemikalije - najbolj znan je lakmusov papir.
💡 Pomni si: V Kislinah je lakmus Rdeč, v Bazah je lakmus Moder!

pH lestvica gre od 0 do 14 in nam pokaže, kako močno kisla ali bazična je neka snov. Je kot termometer za kisline in baze!
Kislo območje : Nižja številka pomeni močnejšo kislino. Želodčna kislina ima pH okoli 2, limonin sok pa pH 2.
Nevtralno območje (pH 7): Čista voda je popolnoma nevtralna - ni niti kisla niti bazična. To je kot srednja točka naše lestvice.
Bazično območje : Višja številka pomeni močnejšo bazo. Milo ima pH 10, čistila za pečice pa lahko pH 13.
💡 Hitro preverjanje: Če hočeš preveriti, ali je Fanta kisla, pomočiš modri lakmusov papir vanjo - če se obarva rdeče, je kisla!

Kisline najdeš povsod: limonin sok (pH 2), kis za solate (pH 2,5) in celo mleko je rahlo kislo (pH 6,5). Tvoja želodčna kislina ima pH med 1,5 in 3,5 - to pomaga pri prebavi hrane.
Med bazami je soda bikarbona (pH 9) odlična za peko in čiščenje. Milo (pH 10) uporabljamo za umivanje, močna čistila za pečice pa imajo pH 13.
Nevtralizacija je kot kemijsko borenje - kislina in baza se "bojujeta" in nastaneta sol ter voda. Formula je preprosta: Kislina + Baza = Sol + Voda.
💡 V praksi: Če te pika čebela (kisel strup), uporabi sodo bikarbone. Če te pika osa (bazičen strup), uporabi kis ali limono!

Nikoli ne poskušaj, vonjaj ali se dotikaj neznanih kemikalij! Vedno uporabljaj zaščitno opremo, če ti tako naroči učitelj. Močne kisline in baze so lahko zelo nevarne.
Nevtralizacija v vsakdanjem življenju je super uporabna. Ko imaš zgago, vzameš zdravilo (antacid), ki je bazično in nevtralizira odvečno želodčno kislino.
Indikatorji iz narave so tudi zanimivi - iz rdečega zelja lahko narediš svoj indikator! V kislinah se obarva rdeče ali roza, v bazah pa modro ali zeleno.
Za teste si zapomni: kisline imajo pH manjši od 7, baze večji od 7, nevtralne snovi pa točno 7. Lakmusov papir je tvoj najboljši prijatelj za prepoznavanje!
💡 Domače eksperimentiranje: Z rdečim zeljem in različnimi gospodinjskimi snovmi lahko narediš svoj kemijski laboratorij - seveda varno!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀
