How do you make a 10% bleach solution?
2. Measure Ingredients
- To make a 1:10 solution, you'll need 1 part bleach for every 9 parts water. A good amount to start with is 1/4 cup bleach and 2 1/4 cup water.
- Carefully pour the bleach into the spray bottle or jar first, then add the water.
How to Make a Five Percent Solution With Salt
- Determine Final Volume. Work out how much salt solution you need.
- Work out Percentage. Work out 5 percent of 200, i.e., (5 ÷ 200) x 100 = 2.5.
- Weigh Salt. Weigh 2.5 grams of salt.
- Dissolve Salt. Pour the salt into a graduated cylinder or volumetric flask containing about 180 ml of water.
- Add Water.
- In biology, the "%" symbol is sometimes incorrectly used to denote mass concentration, also called "mass/volume percentage." A solution with 1 g of solute dissolved in a final volume of 100 mL of solution would be labeled as "1%" or "1% m/v" (mass/volume).
- Together, they make up over 90 percent of all dissolved ions in the ocean. Sodium and Chloride are 'salty.' The concentration of salt in seawater (salinity) is about 35 parts per thousand, on average. Stated in another way, about 3.5 percent of the weight of seawater comes from the dissolved salts.
- Here is the recipe for making hummingbird nectar:
- Mix 4 parts water to 1 part table sugar in a pan. For example, use 1 cup sugar to 4 cups water.
- Bring to a boil then remove from the heat.
- Cover and allow to cool before using or pouring into the storage bottle.
