The hydrogen ion concentration of a solution is indicated by its<br> ___ value.
rosijanka [135]

The hydrogen ion concentration of a solution is indicated by its <u>pH </u>value.

Explanation:

  • A measure of acidity or alkalinity of water soluble substances (pH stands for 'potential of Hydrogen'). A pH value is a number from 1 to 14, with 7 as the middle point.
  • Under normal circumstances this means that the concentration of hydrogen ions in acidic solution can be taken to be equal to the concentration of the acid.
  • The pH is then equal to minus the logarithm of the concentration value.
  • Values below 7 indicate acidity which increases as the number decreases, 1 being the most acidic.
  • The pH of a solution is a measure of hydrogen ion concentration, which in turn is a measure of its acidity.
  • Pure water dissociates slightly into equal concentrations of hydrogen and hydroxyl (OH−) ions. For a neutral solution, [H+] is 10−7, or pH = 7.

A woman produces an egg with 24 chromosomes, including 2 copies of chromosome 21. If the egg is fertilized by a normal sperm, th
Zielflug [23.3K]

Answer:

47

Explanation:

We all know that gametes like egg cell and sperm have haploid set of chromosomes but here as per this question she has produced 2 copies of chromosome 21. For the sake of maintaining haploidy, she was supposed to have only a single copy of chromosome 21 as a result of which her egg cell was supposed to have 23 chromosomes not 24.

But, this is a case of non dis-junction. Also, in a normal sperm there are no such copies of any chromosome i.e. there is a haploid set of chromosomes. It means that sperm must be having only 23 chromosomes. So we can easily infer that when the egg cell and sperm will fuse, the zygote will have 47 chromosomes (24 from egg cell and 23 from sperm).
