How many atoms of chlorine are there in 445g of lead 2 chloride?
To determine the number of atoms of chlorine in 445g of lead chloride (PbCl2), you need to calculate the number of moles of PbCl2 in 445g and then multiply it by the number of chlorine atoms in one PbCl2 molecule. First, calculate the number of moles of PbCl2 using the formula: moles = mass / molar mass. The molar mass of PbCl2 is 278.1 g/mol, so moles = 445g / 278.1 g/mol = 1.6 moles. Since there are two chlorine atoms in one molecule of PbCl2, the total number of chlorine atoms is 2 * 1.6 moles = 3.2 moles of chlorine atoms. To convert moles to atoms, multiply by Avogadro's number. Therefore, there are 3.2 moles * 6.022 x 10^23 atoms/mole = 1.9264 x 10^24 atoms of chlorine in 445g of PbCl2.
Do chlorine tablets get old?
Yes, they do. If you are using the kind of chlorine tablets that dissolve, then they need to be replaced often.
How do you get the ideal reading of chlorine in the pool?
When chlorine enters the water, it is in a form that is an active sanitizer and an oxidizer called "free chlorine". It will react with any number of contaminants in the water. When it reacts with ammonia compounds in the water, which come from bathers' perspiration and urine, it becomes "combined chlorine". In this form, chlorine is a much slower sanitizer. This form also causes chlorine odor and eye irritation. When using the 5-way strip, the difference between the free chlorine reading (pad 1) and the total chlorine reading (pad 2) is the combined chlorine reading.
What if both your free chlorine and total chlorine is low?
Add more chlorine. More to it than that. Test & if necessary correct the pH first - that's important. Calculate correct dose rate of chlorine & add accordingly. If it's an outdoor pool switch to stabilised chlorine if not already using it.
