Flashcards in Solutions And Neutralizations Deck (27)
A solution where water is the solvent
Formulas/ reactions showing the separation of ionic salt in water by dissolving
Solid that “falls” out of solution
Ions that remain in solution after the precipitate reaction has occurred.
In reeks reactions they may be soluble but do not change in oxidation
Special type of double displacement reaction that involves a strong acid and a strong base to produce a salt and water in liquid form.
Naming acids steps:
Binary: -hydro prefix, root of nonmetal element, is ending and acid
Oxyacid:-“ate” ions make “ic” acids
-“ite” ions make “ous” acids
What makes a substance a strong acid or base?
Is dissociates completely
Laboratory technique used when performing a neutralization. Also used to determine the concentration of an unknown.
Do covalent substances dissolve?
Yes but don’t dissociate
The combining of oxygen with other elements (loss of electrons)
The remaining of oxygen from a compound (gain of electrons)
Molarity: concentration unit measured in Mol/L
Where are oxidation sign?
In front of number
Rules of oxidation numbers
Any elemental atom (Fe) or multiple of self (N2) is 0
An ions oxidation number is its charge
Hydrogen’s in +1 except in metal hydrides then it’s -1
Oxygens is -2
The inward force or pull which leads to minimize the surface area of a liquid
Occurs when a solute dissolves
Compounds that conduct an electrical current in an aqueous solution or molten state.
A strong electrolyte has a large fraction of solute that exist as ions
A substance in a redox reaction that donates electrons; in the reaction, reducing agent is oxidized.
A substance in a redox reaction that accepts electrons, in the reaction, the oxidizing agent is reduced.
Metal allowed to corrode in order to save another from corroding.
Transfers electrons to metal that has lost them
Ionic compounds consisting of an atom from an acid and a cation from a base.
The point in a titration where the number of moles of hydrogen ions is equal to the number of moles of hydroxide ions.
The point in titration at which the indicator changes colour
What must happen in order to dissolve
The polar nature of water must be strong enough to overcome the attraction between ions in a compound.
Water is polar and attracted to other parts of molecules, causing them to separate.
Polar molecules attract one another, leads to a dipolar interaction between the positive region of water and the negative region of another. Weak compared to IMF
