What are the possible causes of excessive engine breathing?
Perhaps you could explain your question in different terms.
When you add 20.0 ml to water how do you get the pH of 7.0?
Adding 20 mL fresh pure water to fresh pure water: the pH remain unchanged.
Why is ammonia a tonic and a toxic?
Ammonia is toxic for various reasons:
1) In the ammonium ion form (NH4+), it disrupts Oxidative Phosphorylation by passing through the mitochondrial membrane and messing up the H+ balance.
2) If there is local production of Ammonia as NH3, with a PKa of around 9.3, it will disrupt the H+ balance of the body and hence physiological PH as well
3) It partakes in a redox reaction, hence it disrupts certain redox co-enzyme balances (i.e. NADH/NAD+ and NADPH/NADP+)
-Tosin A.O">">-----------------------------------------------------Ammonia is NEUROTOXIC; it inhibits the formation of neurotransmitters and inhibits the TCA cycle.While those three reasons listed may play a role, MEDICALLY speaking, the mechanism of ammonium neurotoxicity is unknown. Ammonia is extremely toxic to the brain, which is why our livers possess such a great potential for eliminating ammonia as urea. The current accepted hypothesis as to the effect of elevated blood ammonia is centered on glutamate/glutamine/alpha-ketoglutarate metabolism and the net result of inhibiting the synthesis of valuable neurotransmitters.
Increased ammonia results in alpha-ketoglutarate being converted to glutamate and in turn glutamine. The net result of this is twofold. First, there is decreased TCA cycle activity, as alpha-ketoglutarate is part of the TCA cycle, which means less ATP for the brain. Second, and perhaps more importantly, there are decreased levels of GABA and glutamate in the brain. GABA is a major inhibitory neurotransmitter, whereas glutamate is a major excitatory neurotransmitter. Both have many functions.
-A.D.Flat affect is a reduction or absence of emotional expression in one's face, voice, or body language. It can be a symptom of various mental health conditions, such as schizophrenia or depression, and can make it challenging for others to understand or connect with the individual displaying it. Treatment may involve therapy, medication, and social support.
Why does bile make the pH level fall fast?
Bile is alkaline due to its high bicarbonate content, which helps neutralize stomach acid as it enters the small intestine. When bile is secreted, it rapidly increases the pH of the intestinal contents, counteracting the acidity from gastric juices. This process is crucial for creating an optimal environment for digestive enzymes to function properly and for nutrient absorption. Consequently, the introduction of bile can lead to a swift drop in acidity, resulting in a more neutral pH level in the intestine.
The carbon dioxide turns it into bicarbonate, which is an acid. This makes your blood more acidic. When you breathe really fast, you get rid of more of that bicarbonate, which then makes your blood more basic thanks to the acid not being there anymore.
What is the OH- in an oven cleaning solution if the pH is 12.35?
[OH-] = 10-pOH = 10-(14-pH) = 10-(14-12.35) = 10-(1.65) = 0.0224 mol/L
What would be pH of a 0.00884 M solution of HNO3?
HNO3 is a strong acid, which means it dissociates completely. This means you don't have to set up an equilibrium scenario; you can just go with the given molarity as also being the concentration of hydrogen ions [H+]. So, pH = -log(0.00884), which is about 2.05.
How do you calculate how much base to add to increase the pH of the solution?
This depends on what other acids or bases or buffering substances are in solution already, even if pH is neutral!
The most effective way to maintain a stable pH is by the use of a buffer. These are solutions of a weak acid or a weak base, and the conjugate base or acid, adjusted to the desired pH.
What is the acid level of vinegar?
the acid level of lemon juice is less then that of coke or lemon juice. Its pH level is 3, while coke is 2.5 and lemon juice is 2.
What is the effect of decreasing the temperature of the pH of water?
Decreasing the temperature of water the value of pH increase.
For it to be an acid, the pH will have to be less than 7. The strong and more concentrated it is, the lower will be the pH. If it is indeed a strong acid, depending on concentration, the pH could be as low a 0 or 1, but more likely, in a normal lab situation, it will be in the range of 2-4.
First recognize that NaF is the salt of a strong base (NaOH) and a weak acid (HF), so the pH will be alkaline. Next, look at the hydrolysis of NaF: NaF + H2O ---> NaOH + HF, or looking at it another way.... F^- + H2O ---> HF + OH- and here F^- acts as a base, so we need the Kb for NaF and that will be the inverse of the Ka for HF. The Ka for HF is 6.6x10^-4, so Kb = 1x10^-14/6.6x10^-4 = 1.5x10^-11.
Now, Kb = [HF][OH-]/[F-] = (x)(x)/(0.89) = 1.5x10^-11
x^2 = 1.3x10^-11
x = 3.6x10^-6 = [OH-]
pOH = -log 3.6x10^-6 = 5.44
pH = 8.6 (note the pH is alkaline, as expected)
