| 1. | So it has four alkyl groups and potentially carries two negative charges.
|
| 2. | The glass surface has a negative charge due to adsorbed phosphate ions.
|
| 3. | The phosphate group gives the molecules a negative charge at physiological pH.
|
| 4. | Proteins with a negative charge will migrate towards the positively charged anode.
|
| 5. | There, negative charge is drawn to the surface, creating another electric field.
|
| 6. | Albumin has the most negative charge, and will migrate furthest towards the anode.
|
| 7. | The microparticles acquire high negative charges by collecting electrons from the surrounding plasma.
|
| 8. | In addition, the upper layer has more electrons and has slightly negative charge.
|
| 9. | It develops a negative charge, and is the positive terminal of the battery.
|
| 10. | The head of an ionic surfactant carries a net positive, or negative charge.
