Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.

- I just need help in the Calculations EXPERIMENT: ESTIMATION OF SODIUMHYDROXIDE USING HYDROCHLORIC ACID (CONDUCTOMETRIC TIITRATION) Aim: To determine the mass of NaOH in the given solution by conductance measurement. Apparatus & Chemicals: 0.1N, 100 ml HCl , weighing balance, burette, pipette, beaker, funnel, standard flask, glass rod, distill water Theoretical Background: When sodium hydroxide is added to HCl, the highly mobile H+ ions are replaced by less mobile metallic ions. Before the alkali is added, the acid solution has a high conductance due to the highly mobile H+ ions. Observations: Volume of NaOH added (ml) Conductance Volume of NaOH added (ml) Conductance 1 5.5 13 1.3 2 5.3 14 1.0 3 5.1 15 0.7 4 4.6 16 0.4 5 4.2 17 0.1 6 3.8 18 0.5 7 3.3 19 0.9 8 2.9 20 1.2 9 2.6 21 1.7 10 2.2 22 2.2 11 1.9 23 2.5 12 1.6 24 2.9 Calculations:…for a 0.0342 M aqueous solution of aniline, C6H5NH2 (Kb = 7.4E-10), determine the following.

M The number of significant digits is set to 2; the tolerance is +/-4% What is the…MATLAB The acidity of solutions is generally measured in terms of pH. The pH of a solution is defined as theconcentration of hydronium ions. Create a table of conversions from concentration of hydronium ionto pH, spaced logarithmically from 0.001 to 0.1 mol/liter with 10 values. Assuming that you havenamed the concentration of hydronium ions H_conc, the syntax for calculating the negative of thelogarithm of the concentration (and thus the pH) is:pH = -log10 (H_conc)
- just find the fraction. ph was already determined(its not 7.21)Sketch a plot of the fraction of species, f, vs pH for Tyr. Show your calculations for several points on the plot. You want to calculate the fraction of the species for more than 3 of the points. pKa’s for Tyr is 2.24, 9.04, and 10.10.) A truck driver carrying a load of lead nitrate (Pb(NO3)2) lost control of his semi- truck after hitting a patch of ice and crashed the truck into Blue Lake, which was right next to the highway. Despite the best efforts of the emergency workers, several of the crates containing lead nitrate were damaged, and the highly soluble compound dissolved immediately. Assuming the lake is initially at circumneutral pH (7), and that the spill resulted the in a total lead concentration of 10-3 M within the lake. Based on the following information, will PbO(s) precipitate out of Blue Lake. Assume all lead nitrate dissociates into Pb+2 and NO3-, no other sources of lead exist in the lake and that no other reactions besides the equations shown below occur. PbO(s) + 2H+ ⇌ PbO(s) + H+ ⇌ PbO(s) + H2O ⇌ PbO(s) + 2H2O ⇌ Pb2+ + H2O PbOH+ + H2O Pb(OH)2o Pb(OH)3- + H+ logKs0/ksp =14 logK1=3.4 logK2=-0.5 logK3=-12
- Part b As a chemist for an agricultural products company, you have just developed a new herbicide,"Herbigon," that you think has the potential to kill weeds effectively. A sparingly soluble salt, Herbigon is dissolved in 1 M acetic acid for technical reasons having to do with its production. You have determined that the solubility product Ksp of Herbigon is 9.00×10-6 Although the formula of this new chemical is a trade secret, it can be revealed that the formula for Herbigon is X-acetate (XCH COO, where "X" represents the top-secret cation of the salt). It is this cation that kills weeds. Since it is critical to have Herbigon dissolved (it won't kill weeds as a suspension), you are working on adjusting the pH so Herbigon will be soluble at the concentration needed to kill weeds. What pH must the solution have to yield a solution in which the concentration of X* is 4.00×10-3 M? The pKa of acetic acid is 4.76.please give calculation as well. Calculate the pH value of each of the solutions in tubes 1-9 using the Henderson-Hasselbalch equation (H-H eqn).Determine the pl of casein. Compare your experimental values with those found in the literature. Biomolecules. Thank you! The protein is casein.This has got to be one of the worst explanations. No following at all, tried it on a problem 4 different times following the forumla and such and it sucked.
- ΔG° for the dissociation of a weak monoprotic acid in water at 25°C is 28.6 kJ. What is the value of Ka for the acid at this temperature?Insert your answer in E-notation rounded to 2 significant figures.The liquid part of the Moderna vaccine contains a Tris (tromethamine) buffer. The purpose of the buffer is to make the pH level of the vaccine near to that of the human body and also to maintain the integrity of the mRNA component.In a laboratory scale, a biochemist was asked to study the structure of the mRNA component of the Moderna vaccine. To do so, they need to first prepare 500.0 mL of 1.000 M of the Tris buffer solution of pH 7.5000. The available reagents in the lab are the following:Tris base MW = 121.14 g/mol pKa = 8.07Tris-HCl MW = 157.56 g/mol Calculate the amounts of tris base and tris-HCl needed to prepare the buffer solution.Suppose i want to prepare or manufacture 1 litter of Acid free bike or car washing shampoo.
