Where does the term pH come from?
power of Hydrogen
Where did the term pH come from?
Possible 'power of hydrogen' as pH refers to the activity of hydrogen ions in a solution.
How do you determine the pH of each solution?
acidic, neutral, or basic. Salts that form from a strong acid and a weak base are acid salts, like ammonium chloride
What Is the pH of kitchen and bathroom cleaner?
come on people i need to know i am really stuck wiv ma omework
How do you measure the pH of a river?
To measure the pH of a river, you can use a pH meter or pH test strips. Collect a water sample from the river and follow the instructions provided with the pH meter or test strips to obtain a pH reading. Remember to calibrate your pH meter before taking measurements.
How does a large change in temperature or pH affects proteins?
They come apart and lose there shapeA large change in temperature or ph will cause protiens to come apart and lose their shape.
What happen when stomach acid and sodium bicarbonate come together in the small intestine?
When stomach acids, like HCl and pepsin, come in contact with sodium bicarbonate the pH level become more alkaline and less acidic. So the pH level rises.
Where does perm lotion come on the pH scale?
Perm lotion typically has a pH range of around 9 to 9.6, which is considered alkaline. This high pH level helps to break down the disulfide bonds in the hair, allowing it to be reshaped during the perming process.
Why pH for eye drops is 7.4?
The pH of 7.4 for eye drops is chosen because it matches the pH of tears, which are around 7.4. This helps to minimize irritation or discomfort when the drops come into contact with the eyes. Maintaining a pH similar to that of tears also helps to maintain the natural environment of the eye's surface.
Does a pH of 3 have a greater hydrogen ion concentration than a 9 pH?
pH come from "pondus hydrogenii" or "potential hydrogen." It measures the concentration of hydrogen ions. Mathematically, pH = -log[H+] Therefore, to answer your question, a pH of 3 will have a 10-3M of hydrogen ions where as the pH 9 solution will have a 10-9M of hydrogen ions. The lower the pH the higher its H+ concentration and the more acidic it is. (A pH of 9 is actually basic.)
How do you use indicators to measure acidity and basicity?
Many different pH indicators exist, covering different ranges of acidity and alkalinity. Every pH indicator should come with its color guide to help determine the approximate pH level of whatever's being tested. The best way to determine the color's pH indication is a spectrometer.
What is the pH level water?
The pH of pure water should be neutral (7). pH is affected by additives in the water, however, so it will vary depending on the source.
