Detergent has a ph of about 10. is detergent acidic or basic? use figure 8-3 to answer this question.
harina [27]

Answer is: detergent is basic.

pH (potential of hydrogen) is a numeric scale used to specify the acidity or basicity an aqueous solution.  

When pH is less than seven (pH<7), solution is acidic.  

When is equal seven (pH = 7), solution is neutral.  

When pH is greater than seven (pH > 7), like in this example, solution is basic.

For which salt is the aqueous solubility most likely to change by changing the pH of the solution?
Hoochie [10]

The salt whose aqueous solubility will most likely to change the pH of the solution is CaF2(aq).

The pH of a salt solution depends on the nature of the acid and base that forms the salt.

  • Salt of a weak acid and a strong base yields a basic solution
  • Salt of a strong acid and a weak base yields an acidic solution
  • Salt of a strong acid and a strong base yields a neutral solution.

Since HF is a weak acid, its salt CaF2 will be slightly basic when dissolved in water hence the pH of the solution is altered.

Which numerical setup can be used to calculate the<br> atomic mass of the element bromine?
Gekata [30.6K]

Answer:

From the numerical steps highlighted under explanation, the average atomic mass of bromine is 79.91 u

Explanation:

The steps to be taken will involve;

1) Find the number of isotopes of bromine.

2) Identify the atomic mass and relative abundance of each of the isotopes.

3) Multiply the atomic mass of each of the isotopes by their corresponding values relative abundance value.

4) Add the value in step 3 above to get the average atomic mass of bromine.

Now;

Bromine has 2 isotopes namely;

Isotope 1: Atomic mass = 78.92amu and a relative abundance of 50.69%.

Isotope 2: Atomic mass = 80.92amu and a relative abundance of 49.31%.

Using step 3 above, we have;

(78.92 × 50.69%)

And (80.92 × 49.31%)

Using step 4 above, we have;

(78.92 × 50.69%) + (80.92 × 49.31%) ≈ 79.91 u
