Acid dissociation constant

After spending money yet again on chlorine to clean the pool, just about every swimming pool owner has wondered whether common bleach would do the job just as well. In truth, bleach contains the same base chemical as pool chlorine. That chemical is, of course, chlorine. The major differences between the two types are strength and formulation. Also, bleach is a bit less expensive than pool chlorine. Bleach Versus Pool Chlorine Common pool chlorine is made up of the chemical calcium hypochlorite…

This is because in a strong acid/ strong base neutralization, the strong acid and strong base dissociate completely into ions. Therefore, all mole added to the solution would essential react and produce heat. Where as a weak acid would only partially dissociate into ions while the strong base would dissociate into complete ions. Since the weak acid produces less ions to participate in the neutralization, less heat would be produced because…

magazine Nature that bacterial growth and overall metabolism can be inhibited by alterations in the pH of the culture. The active ingredient hypochlorous acid, found in bleach, affects proteins in bacteria by changing the pH of the environment and therefore denaturing them by affecting their secondary and tertiary structures. Moreover, hypochlorous acid has been found to have the same…

We all know that we have our own unique fingerprints but did you know that you can make sun prints? You may be wondering what a sunprint is, a sunprint is like a unique type of photo made with special sunprint paper that with the help of the sun creates a permanent image. A sunprint is formed when a chemical reaction happens with chemicals inside the paper,but before we talk about that, here is how you make a sunprint. You can make a sunprint by placing an object on a sheet of sunprint paper,…

The experiment came out successful based on the results. We did encounter one problem with one of the solutions. The colorimeter results for Biscayne Bay Pond Water didn’t come out right; so we had to dilute the solution to get the result. Analysis: First turn on the colorimeter and select “ALL TESTS” from the testing menu. Press “AMMONIA-N H” from the menu. Fill one tube with 10 ml of DI water, and three tubes with 10 ml of bay water, pond water, and parking lot puddle water. We added a…

If yellow Fever catches you, it will not let you go easily. Hello! I am a new physician from England coming to philadelphia to compare and contrast the French doctor’s who have come straight from the African savanah´s cures to the doctor's degree philadelphia college of physicians cures. I am here by orders from King George the third to write a composition on it. King George sent me so I can decide the best cure, preventing and or curing future yellow fever attacks in England. To do this, i will…

1. Which analytical balance is the more accurate? Why? 2. Which piece of glassware is best at measuring the density of water? 3. What two aspects of the data set you cited in Question 1 define it as “best”? 4. What does “standard deviation” measure? 5. (a) Calculate the standard deviation of the data set you labeled as having the least random error in the first experiment with pure water. (b) Calculate the standard deviation of the data set you labeled as having the MOST random error in the…

Behavioral measurements. Force swimming test (FST). Each mouse was placed into a 20cm diameter glass cylindrical beaker that was filled with warm water (25-30°C) and allowed to swim freely for 6 min. All the experiments were recorded by video. We analyzed the immobility time in last 4 min. Tail suspension test (TST). Each subject was suspended at a hook with tape for 6 min and recorded by video. The immobility time was analyzed in last 4 min. Elevated plus maze (EMP). In the beginning of the…

Bernardi et al., (46) assessed nanoparticle calcium carbonate (NPCC) by means of transmission electron microscopy and the effects of NPCC addition to MTA in regard to the setting time, dimensional change, compressive strength, solubility and pH. , The experimental groups were G1 (MTA), G2 (MTA with 5% NPCC) and G3 (MTA with 10% NPCC). The tests followed ISO and ADA standards. The dimensional change and compressive strength tests were measured immediately after setting, after 24 h and after 30…

Much of the workflow for ceramics production remains the same over the many years this art form has been practiced. When centuries ago, a potter starting the process workflow of producing a ceramic mug (or more likely a jug), he would go to a river bed and collect the clay. Now, Angel Pottery’s supplier is currently a clay supplier in Amherst, Massachusetts. In this supplier’s factory, they use mixing augurs to produce the raw material clay. From factory to home factory, the clay bags are…
