In the estimation of iron(II) by permanganometry, the Mn2+ ion acts as an indicator. The Mn2+ ion itself is colorless in solution. During the titration process, the Mn2+ ion is oxidized to Mn4+ by the iron(II) ion, resulting in a color change from pale pink to colorless. This color change is used to determine the endpoint of the titration.
What it’s the most accurate estimation for 664-127
They are identified in the cavity bb U.S. Pat. 4.512.577and 4.621.813
Fe 2+ is Ferrous Fe 3+ is Ferric
Gee i dont know blue and green .... no no in all seriousness its orange and white
Estimating 26 plus 78 as 25 plus 75 is a form of rounding that simplifies the calculation while maintaining the overall magnitude of the numbers involved. By rounding down to 25 and 75, you are working with numbers that are easier to mentally add together quickly. This estimation technique is particularly useful when you need a rough answer or when exact precision is not necessary.

The copper will appear on the surface of the nail, so it will be different in colour-it'll be like copper.
86 + 40 = 126

To use front-end estimation for 337.4 plus 20.08, we focus on the whole numbers in each value. Rounding 337.4 to 337 and 20.08 to 20, we can add these whole numbers: 337 + 20 equals 357. Therefore, the front-end estimation for 337.4 plus 20.08 is approximately 357.
It is 3+3+4 = 10.
50*7 = 350
20 + 60 = 80
8 + 10 = 18
