pH Levels

NH4Br An ammonium halide that crystallizes in the cubic system; made by the reaction of ammonia with hydrobromic acid or bromine; used in photography and for pharmaceutical preparations (sedatives).

Sabouraud's dextrose agar is primarily used for fungal culture growth as it provides an acidic environment (pH 5.6) that inhibits the growth of bacteria while promoting the growth of fungi. The acidic pH helps in selecting for fungi, as most bacteria do not grow well in such conditions, giving fungi an advantage to grow and form colonies on the agar.

Acids have a pH level lower than 7, typically ranging from 0 to 6.9. The lower the pH value, the stronger the acid.

I dont know, but I think the last guy to answer this wanted you to think that liquid drain cleaner is just as acidic as cucumbers.

To correct the above statement, liquid drain cleaner is NOT an acid, it is a base. Potassium hydroxide has a pH of 14.

The highest pH level of an acid is 0, indicating a very strong acid with a high concentration of H+ ions. The pH scale ranges from 0 to 14, with lower pH values indicating more acidic solutions.

The pH of 0.10 M HBr is approximately 1.0. HBr is a strong acid that completely dissociates in water to produce H+ ions, leading to a low pH value.

The pH level of magnesium acetate would depend on the concentration and purity of the solution. However, typically, magnesium acetate solutions are slightly acidic with a pH range of around 4 to 6 when dissolved in water.

The pH level of a solution containing Ammonium chloride depends on its concentration. However, in general, a 0.1 M solution of Ammonium chloride has a slightly acidic pH of around 5.6-5.8 due to the hydrolysis of the Ammonium ion.

The pH of alum (aluminum sulfate) can vary depending on its concentration and purity. Typically, a solution of alum will have a pH around 3-4, making it acidic.

The average pH level of humans' stomach acids are 1.2-3.6

The normal pH of semen is 7.2-8.0 so somewhat alkaline.

No, a buffer does not always hold the pH of a solution at pH 7. A buffer is a solution that can resist changes in pH when an acid or base is added. The actual pH at which a buffer solution can effectively resist changes depends on the specific components and their concentrations in the buffer system.

The pH of prostatic fluid is typically around 7.2 to 8.0, making it slightly alkaline. This alkaline pH helps to neutralize the acidic environment of the vagina and protect sperm as they travel through the reproductive tract.

Yes, bleach typically has a pH level above 7, making it an alkaline substance. The pH of bleach can vary depending on the concentration and formulation of the product.

Your body naturally maintain pH through various reactions. Mostly, it can maintain pH through cravings. Your body may need to lower its' acidity, so you would have cravings for something that's more neutral or leaning toward being a base. Or the other way around. The same thing happens for nutrition. If your body is severely deficient in some vitamin or mineral, you would have cravings for something with high concentrations of that vitamin or mineral. i.e. low in potassium could result in cravings for bannas.

The paragraph above was written by someone else and explains an idea that has been popular for thousands of years, but which has never been shown in objective research. For example, many iron deficient people tend to crave ice, which usually has very little iron.

ANYway, our bodies control pH very carefully. Just a small deviation either way can kill us. One way we add acid is by producing hydrochloric acid in our stomachs and then absorbing that from our intestines. One way we add base is to produce sodium bicarbonate in our pancreas, also absorbed from our intestines. Breathing deep and hard will RAISE body pH; holding breath or breathing too little can LOWER it. There are a lot of other things at play here. Generally, our bodies take care of this without our attention. Thank Goodness!

^^^Sooo complicated

There are two main ways our body controls pH

Respiratory system via CO2 (carbon dioxide - acidic)

Metabolic (renal) system via HCO3 (bicarb - alkalotic)

P.S.

Previous editor, breathing deeply blows off your CO2 which raises pH making you more alkalotic

Holding your breath retains CO2 lowering pH making it more acidic

The optimum pH level for lactase, the enzyme that breaks down lactose, is around 6.5 to 7.5. This pH range allows for optimal activity of the enzyme, leading to efficient breakdown of lactose into glucose and galactose. Deviation from this pH range can reduce the effectiveness of lactase in digesting lactose.

The stronget base would be something like lye with a Ph level of 14.

Enzymes have an optimal pH at which they work most efficiently, but some enzymes can function over a range of pH levels beyond their optimal pH. However, extreme pH levels can denature enzymes, leading to loss of their function.

The solution has become less acidic and more neutral as the pH has increased from 5 to 7. A pH of 5 is acidic and a pH of 7 is considered neutral on the pH scale, which ranges from 0 (most acidic) to 14 (most basic). The change indicates a decrease in the concentration of hydrogen ions present in the solution.

The pH of a solution of Na2S (sodium sulfide) depends on its concentration. When Na2S dissolves in water, it forms hydroxide ions which makes the solution basic. Therefore, the pH of a solution containing Na2S would typically be greater than 7.

The pH of a solution of NaHSO4 would depend on its concentration. However, for a dilute solution, NaHSO4 would be slightly acidic with a pH below 7 due to the presence of the sulfate ion and its limited hydrolysis in water.

pH can be measured using a pH meter, pH strips, or pH indicator solution. A pH meter provides a numerical value for pH, while pH strips or indicator solution change color based on the pH of the solution being tested.

The pH level of Sweet 'N Low is around 5.5-6.5, making it slightly acidic.

The nucleus of a cell does not have a steady-state pH value, as it is surrounded by the cytoplasm. The pH within the nucleus can vary based on the specific cellular processes happening at any given time.

Here is a website that tells what the pH of eggwhites are, I haven't seen anything about total pH, perhaps some nice person will steer us in the right direction.
