What substance would you add to to form a buffer solution CH3COONa?
Ch3cooh
Substances would act like a buffer when combined in equal amounts?
CH3COOH and CH3COO- CH3NH2 and CH3NH2H+
How many hydrogen atoms are in CH3COONa plus H2O plus CO2?
Dissolving in water = splitting in ionsCH3COONH4 --> CH3COO- + NH4+CH3COO-, acetate is a weak base: CH3COO- + H2O CH3COOH + OH-NH4+, ammonium is a weak acid: NH4+ + H2O NH3 + H3O+Totally in water: CH3COO- + NH4+ CH3COOH + NH3 and 2H2O H3O+ + OH-
What substance acts to prevent sudden pH changes in bodily fluid?
Buffer
How to represent the buffer solution?
In general, a buffer system can be represented by writing a salt followed by slash and an acid or conjugate base followed by slash and an acid like salt/acid or conjugate base/acid. Thus, the sodium acetate-acetic acid buffer system can be written asCH3COONa/ CH3COOH or CH3COO-/CH3COOHSimilarly, ammonia-ammonium chloride buffer system can be represented asNH3 / NH4+Note that NH4+ is an acid and NH3 is a conjugate base according to Lewry-Bronsted concept.
What substance would you add to to form a buffer solution CH3COONa?
Ch3cooh
Why a mixture of ch3cooh and ch3coona can act as a buffer while a mixture of hcl and nacl cannot?

Why a mixture of ch3cooh and ch3coona can act as a buffer while a mixture of hcl and nacl can not?
Buffers are made out of what are called weak acids or weak bases. Mixtures of CH3COOH and CH3COONa can act as buffers because they don't break apart completely in solution like HCl and NaCl. As the CH3COOH and CH3COONa are in solution they keep the pH constant by either donating or accepting protons because they don't act like strong acids or bases. HCl is known as a strong acid where the hydrogen disassociates completely from the chloride. NaCl is not a buffer because it dissolves completely as welll
A solution that is resistant to change in pH?
Solutions that resist change in pH when added to a strong acid or base are known as buffer solutions.
What is the chemical reaction when baking soda is mixed with vinegar?
CH3COOH + NaHCO3 = CH3COONa + CO2 + H2O
What is the equation for aqueous acetic acid with aqueous sodium hydroxide?
CH3COOH + NaOH = CH3COONa + H2O
Comlpete molecular equation of acetic acid and sodium hydroxide?
CH3COOH+NaOH=CH3COONa+H2O
What are the products of the reaction between acetic acid and sodium hydroxide?
the products are CH3COOH + NaOH ------CH3COONa + H2O
What is the balanced equation for acetic acid and sodium hydrogen carbonate?
CH3COOH + NaHCO3 ---> CH3COONa + H2O + CO2
What is the neutralization equation of hc5h7o5co2 and nahco3?
nahco3 + ch3cooh --> co2 + CH3COONa + h2oNote: it is CH3COONa (sodium acetate) and not na2co3(sodium carbonate) as stated in the question above
Why does a mixture of acetic acid and sodium bicarbonate release carbon dioxide?
CH3COOH + NaHCO3 --> CH3COONa + H2O + CO2
What is the formula for sodium ethanoate?
CH3COOH + NaOH -----> CH3COONa + H2O(Ethanoic acid) (Sodium hydroxide) (Sodium Acetate) (Water)
