## What is 1 ppm equal to?

One ppm is equivalent to 1 milligram of something per liter of water (mg/l) or 1 milligram of something per kilogram soil (mg/kg).

## How do I make a 1000 ppm solution?

1g Na in relation to FW of salt = 58.44 / 23 = 2.542g. Hence, weigh out 2.542g NaCl and dissolve in 1 liter volume to make a 1000 ppm Na standard.

## How can we prepare 0.1 N NaOH in 100 ml?

To make 1N NaOH solution = dissolve 40 grams of NaOH in 1L of water. To make 0.1N NaOH solution = dissolve 40 grams of NaOH in 1L of water. For 100 ml of water = (4/1000) × 100 = 0.4 g of NaOH. Thus, the amount of NaOH required to prepare 100ml of 0.1N NaOH solution is 0.4 g of NaOH.

## What is blood a solution of?

The liquid portion of the blood, the plasma, is a complex solution containing more than 90 percent water. The water of the plasma is freely exchangeable with that of body cells and other extracellular fluids and is available to maintain the normal state of hydration of all tissues.

## Is blood is an example of colloid?

Blood has the characteristic of both a colloid and a suspension making it a colloidal suspension. In its normal stable state, blood is a suspension, which is a colloid. It mainly consists of red & white blood cells, and lymphocytes suspended in plasma.

## Is gelatin a solution colloid or suspension?

The ingredients of gelatin are completely soluble in water and the end product is clear and transparent. It is a solution, in my opinion.

## Is blood a colloid solution?

Blood is a colloid because in blood the blood cell size is between 1nm to 100nm. A mixture in which one substance is divided into minute particles (called colloidal particles) and dispersed throughout a second substance. The mixture is also called a colloidal solution, colloidal system, or colloidal dispersion.

## Is gelatin a colloid?

Gelatin, when dissolved in water, is a colloid because the protein molecules that compose it, mostly derived from collagen, are much larger than usual dissolved molecules, but they remain evenly dispersed throughout the water. A gel is another type of colloid, where a liquid is dispersed through a solid.
