How to find pH using concentration and key?
Once you know the acid or base concentration of your sample, along with the key, you can determine the sample’s actual ph It’s important to recognize that the pH meter reading you get from your sample won’t be an exact value. The meter reading will be an approximate value that falls somewhere between the low and high end of your key’s scale. To find the actual pH of your sample you will need to multiply the meter reading by the key’
How to find pH using wavelength and concentration?
If you have a known solution of an acid or base, you can easily find the ph using a pH meter. You can also use a color indicator strip and a standard solution of known pH, then measure the color change of an unknown solution to find its pH. If you don’t have a color indicator, use the color of an acidic or basic dye to match the color of a known solution to your color change.
How to find pH of water using concentration and wavelength?
If you have a colorimeter and know the values that correspond to the colors of acidic, neutral, or basic water (see table below), then all you have to do to calculate the water's pH is to enter the color value into your pH meter and read the result. Using a colorimeter is the most accurate way to measure the color of water because it doesn't depend on the manufacturer of the meter or the color of the liquid container.
How to find pH using concentration and wavelength?
Considering the importance of pH in water, it is very important to determine the value of the water’s pH. This can be easily done by using the color of water. Generally, water with a lower pH is lighter in color, while water with a higher pH is darker.
How to find pH of ppt solution using wavelength and concentration?
The wavelength is the length of a single vibrating wave of light. A solution’s refractive index is a measure of how much light bends as it passes through it. The refractive index of water (RI = 1) is lower than most organic compounds so generally the absorption of light by water is lower than by other compounds. Since a lower absorption of light is an indicator of higher pH, water’s lower refractive index allows for easier detection of higher pH. Another approach to
