What are burrettes used for?
Burettes are used in chemistry laboratories to accurately measure and dispense volumes of liquid. They are commonly used in titration experiments to slowly add a solution to another solution until a chemical reaction reaches completion.
How much solution to 1 liter water 110 dilution?
You add 9.09ml of stock solution to a volumetric and make it up to 1 litre to get a 110 dilution
What happen when you add table salt and iron filings?
When you add table salt and iron filings together, they do not react chemically. The salt and iron filings will remain as separate entities in the mixture.
Why does manufacturers place metallic iron in cereals?
Some manufacturers add metallic iron to cereals as a source of iron fortification, to help combat iron deficiency. Iron is an essential mineral for the body, especially for proper blood cell function. This fortification can be beneficial for individuals who may not be getting enough iron in their diet.
What is the procedure for conducting a titration using H3PO4 as the titrant?
To conduct a titration using H3PO4 as the titrant, first prepare a solution of H3PO4 of known concentration. Then, add the H3PO4 solution to the analyte solution (the solution being titrated) using a burette until the endpoint is reached. The endpoint is typically indicated by a color change or a sudden change in pH. Record the volume of H3PO4 solution used at the endpoint to calculate the concentration of the analyte.
What is the oxidation number of H in H3PO4?
The oxidation number of H in H3PO4 is +1. In a compound, the oxidation numbers of all the elements add up to the overall charge of the compound, which is 0 in this case. Since the oxidation number of oxygen is typically -2 and there are four oxygen atoms in H3PO4, the oxidation number of hydrogen must be +1 to balance the charge.
What is the formula weight of H3PO4?
Hydrogen=1.008*3 Phosphorus=30.974 Oxygen=16.00*4 Add all of them up=97.998
What do you add to sulpuric acid to get iron sulphate?
You would add iron oxide (rust) to sulfuric acid to produce iron sulfate and water in a chemical reaction.
How many moles of O2 are in one mole of H3PO4?
Actually H3PO4 is a molecular formula referring to the compound we know as Phosphoric acid. It doesn't indicate number of moles of H3PO4. But the number of moles can be found out if the amount in mass or some other measurable quantity(e.g. conc. in solution) is given. The molar mass(mass of 1 mole) of H3PO4 is 98 grams. So if mass is given then it can be converted to grams and dividing by molar mass(i.e 98) we get number of moles. moles of H3PO4 =(mass of H3PO4 in grams)/98. 1 mole of H3PO4 has ->3 moles of H atoms. ->1 mole of P atoms. ->4 moles of O atoms. ( 1 mole=6.0225 *1023 units)
If you add iron and oxygen?
If you add iron and oxygen, the iron will undergo a chemical reaction called oxidation, forming iron oxide, commonly known as rust. This process occurs more rapidly in the presence of moisture, as water facilitates the oxidation of iron.

How can I effectively add iron to plants?
You can effectively add iron to plants by using iron chelates or iron sulfate as a soil amendment, applying foliar sprays containing iron, or using iron-rich fertilizers. It is important to follow the recommended dosage and application instructions to prevent damage to the plants.

What must you add to iron to make mild steel?
The important element to add is chromium.
