What is a true statement about weak electrolytes?
Weak electrolytes are substances that partially dissociate into ions in water, resulting in a low conductivity compared to strong electrolytes. They include weak acids, weak bases, and some salts. Weak electrolytes do not completely ionize in solution, leading to a reversible reaction dynamic.
What can be said about the conductivity of aqueous solutions of inorganic compounds?
The conductivity of aqueous solutions of inorganic compounds largely depends on their degree of dissociation into ions. Strong electrolytes, such as soluble salts, acids, and bases, fully dissociate in water, resulting in high conductivity due to a greater concentration of ions. In contrast, weak electrolytes only partially dissociate, leading to lower conductivity. Additionally, the mobility of the ions, influenced by their charge and size, also plays a significant role in determining the overall conductivity of the solution.
Can every strong electrolyte be considered a strong acid?
No, not all strong electrolytes are strong acids. Strong electrolytes include strong acids, strong bases, and soluble salts. Strong acids are a subset of strong electrolytes that fully dissociate into ions when dissolved in water, leading to a high concentration of ions in solution.
What kind of substances can electric current can flow through?
Electric current can flow through conductive materials such as metals (copper, silver, aluminum), electrolytes (saltwater, acids), and certain semiconductors (silicon, germanium). Insulating materials, like rubber and plastic, do not allow electric current to flow.
Why does a pineapple conduct electricity?
Biological materials, such as this one, will usually conduct electricity due to ions in the liquid. Since an ion has an electrical charge, and is relatively free to move around, it can conduct an electrical current.
Are all acid solutions strong electrolytes?
Not all acid solutions are strong electrolytes. Strong acids, such as hydrochloric acid, sulfuric acid, and nitric acid, completely dissociate into ions in solution, leading to strong electrical conductivity. Weak acids, such as acetic acid, only partially dissociate, resulting in a lower concentration of ions and weaker electrical conductivity.
Which phrase is not true about strong acids?
"Strong acids are weak electrolytes" is not true about strong acids. Strong acids completely dissociate in water to form ions, resulting in strong electrical conductivity.
Strong electrolytes are those in which?
Strong electrolytes are substances that completely dissociate into ions when dissolved in water, leading to high electrical conductivity. Examples include strong acids, strong bases, and soluble salts.
Are string acids strong electrolytes?
No, most organic acids, including string acids, are weak electrolytes. This means they only partially dissociate into ions in water, resulting in a lower conductivity compared to strong electrolytes like strong acids or salts.
How does acid strength affect electrical conductivity?
The strength of an acid depends of the number of hydrogen ions in solution- the stronger the acid the more hydrogen ions there are in solution. Hydrogen ions in solution carry current, therefore the more hydrogen ions in the solution the more current there will be carried through solution.

Are strong acids poor electrolytes?
All acids and bases are electrolytes. However, the strong acids or bases are strong electrolytes, and the weak acids or bases are weak electrolytes. Electrolytes are substances, that when dissolved in water, produce ions capable of conducting electricity. Sodium hydroxide (NaOH) is a strong base, and strong electrolyte. Hydrogen bromide is a strong acid, and also a strong electrolyte. Ionic compounds generally form good electrolytes because they completely ionize when dissolved in water, and can then conduct electricity. Gatorade can be marketed as an "electrolyte containing beverage" because when the ionic salt, NaCl (table salt) or KCl, is added to water, it ionizes into Na+ and Cl-, which then are able to conduct electricity. Pure water is a very weak base, and bad conductor of electricity; there aren't enough free ions to carry a charge. We need electrolytes for conduction of nerve impulses, which are electrical. The reason why we even consume sports drinks is because we lose ionic salts in our sweat. Loss of too much salt through perspiration, and intake of too much pure water, diminishes our ability to conduct nerve impulses - which results in cramping, fatigue, and in extreme cases, death. In short, sports drinks are, without sugar and flavoring, just water with small amounts of different salts thrown in - and acids and bases are electrolytes.

Make a table that compares at least 3 properties of acids and bases?
| Property | Acids | Bases | |----------------|-------------------------------------------|---------------------------------------| | pH | pH less than 7 | pH greater than 7 | | Taste | Sour | Bitter | | Conductivity | Weak electrolytes | Strong electrolytes |

No, not all strong electrolytes are strong acids. Strong electrolytes include strong acids, strong bases, and soluble salts. Strong acids are a subset of strong electrolytes that fully dissociate into ions when dissolved in water, leading to a high concentration of ions in solution.
