Answer:
OH-
Explanation:
it's consists of an oxygen and hydrogen atom held together by a covalent bond and carries a negative electric charge
Condensation
..when gas cool down into liquid statr its called condensation..
<span>We know that density is equal to mass divided by volum, D=M/V and in this case we have 1 gallon of a solution of sulfuric acid with 37.4% of concentration in mass.
1 gallon is 3785.41 ml and according the formula M=D*V = 1.31 * 3785.41 = 4958.89 grams of solution.
Only 37.4% of the solution is sulfuric acid, that is 4958.89 * 37.4/100= 1854.62 grams
Then the number of grams of sulfuric acid is 1854.62 gr.</span>
Answer : The concentrations of hydroxide and hydronium ions in a solution with a pH of 10.2 are, and respectively.
Explanation : Given,
pH = 10.2
pH : It is defined as the negative logarithm of the hydrogen ion concentration.
First we have to calculate the hydrogen ion concentration
Now put the value of pH in this formula, we get the hydrogen ion concentration.
Now we have to calculate the pOH of the solution.
Now put the value of pH, we get the value of pOH.
Now we have to calculate the hydroxide ion concentration
Now put the value of pOH in this formula, we get the hydroxide ion concentration.
Therefore, the concentrations of hydroxide and hydronium ions in a solution with a pH of 10.2 are, and respectively.
