How to tell if teeth/gums are weak?

Strong/weak acids and bases - how to tell?

  • 1. How can I tell if something is an acid or a base? 2. Once that is determined, how can I tell if it is a strong or weak acid/base? Thanks so much!

  • Answer:

    It's just very simple: you can use litmus paper or pH indicator, also known as pH paper. Normally, the indicator causes the colour of the solution to change depending on the pH. Solutions with a pH value above 7.0 are basic, and solutions with a pH value below 7.0 are acidic. Solutions with a pH value of 7.0 are neutral. Acid: red Base: blue Well, you can determine it easily, but you have to use the pH measurement for exact measuring.

Let me see if I remember this correctly... Acid is going to be a proton donor, or electron acceptors Pretty much ANYTHING with H at the BEGINNING of the name will be acidic - HCl, HCN, H2SO4, H3(PO4)2, They are going to have a H+ that they want to give away. When the H goes away from it, the electrons that were shared between the H and the rest of the compound are BOTH going to stay with the compound (even the one that belongs to the H), hence electron acceptors. Bases: Proton acceptor, electron donor. Want to gain that H+, and lose some electron density to the H when it gains it. Sometimes have H @ the end, I guess? I can't even remember if there was a good rule for this or not. Strong acids: Dissociate 100% in water There are either 4 or 6, don't remember though The ones I know: HOCL, HCl, HI, HF (I think), maybe H2SO4. There are a couple more than that. Strong bases: Dissoc. 100% in H2O any group 1 or 2 metal with OH or (OH)2 is going to be a strong base. There are a few more that are exceptions (that are not group 1 or 2 metals with OH, but are still strong bases. Google that. I'm sure you can find the specific ones. If I'm not mistaken, the stronger acids are going to be the ones with the more electronegative part that isn't H. So whatever the other part is, the closer it is to F, the more strongly acidic it will be.

with bases you can pour drops of it on your hand and rub it, if it is slippery then it is a base, you can tell a base from the smell. whereas with acids they dont have scents. strong acids almost completely dissociate in water but weak acids only give a small amount of ions when dissolved.

1.if the solution is bitter , turns litmus colour to blue than it is a base and if it turns it tu red and is sour in taste than it is acid 2.Strong Acid-By using pH Scale and by determining amount of hydrogen ion it give Strong Base-pH Scale and by calculating the amount of hydroxyl[OH] ion it give
