- HCl, HI, HBr, HNO3, H2SO4, HClO4
- What are the strong basses?
- IA, IIA
- What are the soluble salts?
- salts are ionic compounds composedd of cations other than H+ and anions other than OH-
- What is a weak base?
- interacts with water to yield a limited # of ions
- What are compounds that are water soluble but do not dissociate into ions?
- What are single replacement reactions?
- are reactions in which electrons are transferred from one of the particles to another of the particles
- What is another name for a single-replacement reaction?q
- oxidation-reduction reactgion
- What is the loss of electrons called?
- What is the gain of electrons called?
- How do you find the total pressure of a gas?
- Pressure of the hydrogen collected and the pressure of the water vapor collected
- What does the ideal gas law state?
- What happens when two ionic solutions are mixed possibly?
- a precipitate may form
- What is a double replacement reaction involve?
- a precipitate
- What happens in a double replacement reaction and what is another name for it?
- the ions are exchanged but the oxidation states do not change, metathesis reaction
- What is an eudiometer?
- collects hydrogen gas produced in a gas-collection tube
- How do you find the percent yield of a product?
- actual yield/theoretical yield, theoretical being max from equation
- What is the synthesis reaction used for?
- to produce a precipitate of aspirin and determine the purity of the aspirin and how much of the aspirin was actually yielded
- What is an acid?
- any compound that will donate a hydrogen ion in a chemical reaction
- What is a base?
- any compound that will accept a hydrogen ion in a chemical reaction
- When is an aqueous solution is considered acidic and what solution is considered basic?
- acidic-when the H30 ion concentration is greater than the OH ion molarity, and basic when reversed
- When does phenolphtalien turn pink?
- in a base
- What is an acid/base reaction?
- when the acid donates a hydrogen ion to the base to yield a product
- What is titration used for? and what is it?
- it allows to find the amount of either the base or an acid, involves the addition of known conc. to unknown concentration until equiv.
- What is the equivalence point?
- What is the importance of litmus paper/
- blue litmus paper remains blue in basic and red in acidic solution, red litmus remain red in acidic and blue in basic
- What is a standard solution?
- a known concentration solution
