Study Notes
Acids (ACID)
- Acids waxay leeyihiin pH ka hooseeya 7.
- Acids magacooda si guud loogu yaqaan inay yihiin xasaasi.
- Acids kiimiko ahaan waxay soo saaraan ion H+ (proton) marka la dhoobo.
- Acids xoog leh sida HCl, H2SO4, iyo HNO3 waxay leeyihiin pH ka hooseeya 3.5.
- Acids daciif ah sida CH3COOH waxay leeyihiin pH u dhexeeya 3.5 ilaa 7.
- Acids wanaagsan waxay khatar keeni karaan oo ay sababi karaan gubasho.
- Haddii H+ ion lagu shubo (dhalkeedi) waxay sababi kartaa in deegaanka ay noqoto acidic.
- Acids waxay leeyihiin saameyn weyn oo xagga kiimikada ah, sida wadarta deegaanka.
Bases (BASE)
- Bases waxay leeyihiin pH ka sareeya 7.
- Bases magacooda si guud loogu yaqaan inay yihiin badnaan macnaheeda tirtir.
- Bases kiimiko ahaan waxay soo saaraan ion OH- marka la dhoobo.
- Bases xoog leh sida NaOH, KOH, iyo Ca(OH)2 waxay leeyihiin pH u dhexeeya 7 ilaa 10.5.
- Bases daciif ah sida NH4OH waxay leeyihiin pH u dhexeeya 10.5 ilaa 14.
- Iyada oo la isticmaalayo bases, ion OH- ayaa laga dhex helaa.
- Bases waxay door muhiim ah ka ciyaaraan falanqaynta kiimikada iyo wax-soo-saarka.
- Bases waxay la shaqeeyaan acids si ay u sameeyaan falcelinno kiimiko oo kala duwan.
