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 definition for Plant Acid?
Plants that demand a soil pH lower than 6.
How do you measure the pH of a river?
all you need is some pH tape/paper. it should come with a color wheel, you dip the pH paper in the water and match the color and it should tell you the number
What Is the pH of kitchen and bathroom cleaner?
come on people i need to know i am really stuck wiv ma omework
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 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.
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 are two ways that science measures pH?
There are several dyes that change color with pH, and come with a chart showing what color equates to what pH. These are better to use than litmus paper because, while litmus will show you whether the solution under test is acidic or alkaline, these newer dyes will show you the pH.Dye-based pH tests have a big problem: they're only accurate on colorless solutions. This is why pH meters, which test pH electronically, are so good - they don't care what color your material is.
What is the most acidic pH 10 pH 3 pH 2 pH 6 pH 8 pH 12 pH 1 pH 75?
PH 75 is the most acid.
