The balanced equation is HCOOH(aq) + H2O(l) gives HCOO- (aq)+ H3O+ (aq)
Ka*kb= Kw
Kw= dissociation constant of water= 1*10-4
Kb= kw/ka= 1*10-4/ 1.7*10-4 =0.588
The connugate base of formic acid is formate anion.

Carboxylic acids are organic compounds that have the general formula RCOOH where Ris any carbon-containing group. They all have the following structure: R-C-O-H Acetic acid is a carboxylic acid in which R CH3. (CH3 is called a "methyl" group.) Formic acid is the simplest organic acid in which RH. The Ka for formic acid is 1.7 x 10-4. Write the balanced equation for the reaction offormic acid with water. What is the name and Kb for the conjugate base of...

Ammonia, NH3, is a weak base because a proton can readily bind to the lone pair on the nitrogen to produce the ammonium ion, NH4+. Organic compounds that contain nitrogen are also weak bases for the same reason. Amines are compounds derived from ammonia in which one or more of the hydrogens are replaced by a carbon-containing group (R). The simplest amine is methylamine in which is a "methyl" group, CH3. Its kb is 4.4 X 10-4. Write the balanced...

Name Time 4) The study of carbon-containing compounds and their properties is called organic chemistry, Besides carbon atoms, organic compounds also can contain hydrogen, oxygen, and nitrogen atoms (as well as other types of atoms). A common trait of simple organic compounds is to have Lewis structures where all atoms have a formal charge of zero. Consider the following incomplete Lewis structure for an organic compound called histidine (an amino acid), which is one of the building blocks of proteins...

in some cases, there may be a mixture of two or more acids. When this happens, the stronger acid will dissociate completely, so you should be able to calculate how much H,0 is in solution as a result. Writing out the equation for the dissociation often helps The weak acid will attempt to dissociate and is governed by the equilibrium (K,). You should write out the equation for the weak acid Now-write in the values for the concentrations that you'll...
