Calculate the concentrations of H3O+ and the pH of each acidic solution. Since HCl is a monoprotic acid (an acid that donates only one proton or hydrogen atom permolecule to an aqueous solution), the H3O+ concentration is equivalent to the HCl molarity
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.
HERE ARE THE QUESTIONS TO THE LAB THAT WAS ALREADY COMPLETED. I WILL POST THE LAB NOTES AT THE BOTTOM OF THE PAGE.. Calculate the concentrations of H3O+ and the pH of each acidic solution. Since HCl is a monoprotic acid (an acid that donates only one proton or hydrogen atom permolecule to an aqueous solution), the H3O+ concentration is equivalent to the HCl molarity. Summarize your results for each pH indicator, recording both the pH values and the color of the solution at each pH..Tube #[H3O+]pHbromothymol bluemethyl yellowbromocresol greenred cabbage extract12345672. Estimate the useful range for each indicator, from a minimum to maximum pH. The range usually spans 1.5 to 2 pH units. For example, bromphenol blue is considered to be useful in the range from 3.0 to 4.6.pHbromothymol blue methyl yellow bromocresol green red cabbage extract 3. Which indicator is the best to use for observing pH changes around pH = 2, pH = 4 and pH = 6?Experiment 21. Calculate the concentrations of OH- and the pH of each basic solution. Since NaOH donates one OH- ion for each NaOH molecule, the OH- concentration is equivalent to the NaOH molarity. The pOH is calculated as -log[OH-] and the pH is calculated as 14 – pOH.

Label one test tube “#1.†From the Materials shelf, add 5 mL of 0.1 M hydrochloric acid (HCl) and 5 mL of water to #1.(Double-click on a test tube to label it.)3. Label each of the remaining test tubes, #2 – #7. Add 9 mL of water to the each of them.4. You will now create a series of successively diluted acidic solutions as follows:(a) Pour 1 mL from #1 into #2.(b) Pour 1 mL from #2 into #3.(c) Pour 1 mL from #3 into #4.(d) Pour 1 mL from #4 into #5.(e) Pour 1 mL from #5 into #6.(f) Pour 1 mL from #6 into #7.5.
