A different type of Japanese bamboo had been studied by Phong et al. (2012). Moso bamboo was harvested and processed using several methods to obtain the fiber. In alkali extraction method, the bamboo was cut into thin slabs with length and thickness of 25 cm and 3 mm, respectively. The slabs were immersed in different concentration NaOH solution (1%, 2%, 3%) at 70 ⁰C for 10 h. This study showed that only 1% NaOH resulted in higher mechanical properties. The roller looser was then used to produce…
Nimodipine 0.02% solution contains the following excipients:
Ethanol 96%, Macrogol 400, sodium citrate, citric acid, Water for Injections Ph. Eur.
These excipients consist of properties that aim towards the proper functionality of Nimotop. They consist of inherent stabilities that cause little or no effect in the stability of the drug and they do not have any acute or chronic toxicity. The excipients are also added into the Nimodipine 0.02% solution to enhance the biological…
Analysis of Chemical Equilibria
The reaction being done with borax and HCl is an acid base reaction. The K constant expression of the reaction is Kc = [Na^+][B4O7^-2]. A titration is needed for this experiment because when a strong acid with a known concentration is added to a weak base, the unknown concentration of the weak base can be found, which can then find the moles of the weak base, which can then find the Kc. The first law of thermodynamics is that energy can’t be created…
Since the Copper (Ⅱ) Sulfate is in powdered form, it will naturally diffuse into the air. Therefore, between the time the hydrated compound is measured and the experiment is conducted, there will be a loss of mass. One way to prevent this error is to weigh the mass in a sealed container which would prevent the mass from diffusing into the…
To determine optimal pH value for the hydrolysis of p-NPG by leukocyte GCase, we examined effects of variable pH (4.0-5.5) at a constant substrate concentration (5mM). Figure 1 shows the pH activity curves of leukocyte GCase assayed in the presence and absence of 6 mg per ml Sodium taurocholate. In the absence of the pure sodium taurocholate, the activity in the range of pH 4.0-4.8 was considerably lower. However, in the presence of pure Sodium taurocholate, leukocyte GCase was optimally active…
Title: How does the amount of baking soda affect its reaction with vinegar?
Aim: To find out how different amounts of baking soda (soda bicarbonate) affect the length of its chemical reaction with vinegar (acetic acid).
If the amount of baking soda is increased then the length of its reaction with vinegar will increase because there will be more soda bicarbonate for the acetic acid to react with.
What are buffer solutions?
Buffer solutions are solutions in water that mark the mixture of acids and bases. They assist in neutralization response to a certain quantity. Acidic buffer answers are those that have robust acids and weak bases as their components. they're used for neutralizing alkaline solutions. Alkaline or primary buffer answers are those who have sturdy alkalis and weak acids within themixture. they're used for neutralizing acidic aqueous answers.

ACID-BASE PROPERTIES OF SODIUM CHLORIDE, SODIUM FORMATE AND AMMONIUM CHLORIDE
The objective of this experiment is to examine the definitive characteristics of acids and bases by investigating the characteristics of strong versus weak acids; more specifically, why these differences are important in the process of titrations. In this experiment, there are two titrations performed and measured the pH of one salt solution. This experiment includes a strong acid and strong base…
The aim of this experiment is to determine through calculations the concentration of acetic acid content within a common white vinegar.

Bases are cations that have a hydroxide anion added into their molecular formulas. Bronsted defined bases as a proton acceptor.3 Just like acids, bases can be either strong or weak. Strong bases completely dissociate their OH- after a reaction and weak based only partially dissociate their OH-.3 Meaning strong bases cannot return to their initial state, yet weak bases can return to their initial state.
Vinegar, common in…
