Write a chemical equation showing how this is an acid according to the Arrhenius definition. Express your answer as a balanced c
1 answer:
Answer:
Explanation:
Arrhenius theory:-
The Arrhenius theory was introduced introduced by Swedish scientist named Svante Arrhenius in 1887.
According to the theory, acids are the substances which dissociate in the aqueous medium to produce electrically charged atoms ( may be molecule). Out of these species furnished, one must be a proton or the hydrogen ion, .
So,
The expression for acid, is:-

Answer:
1,06 g of NaNO₃ and 1,42 g of Na₂SO₄
Explanation:
In water, NaNO₃ and Na₂SO₄ dissociates as:
NaNO₃ → Na⁺ + NO₃⁻
Na₂SO₄ → 2 Na⁺ SO₄²⁻
The ionic strength is difined as:
∑ Where Ci and Zi are concentration and charge of each ion in solution. Thus:
= 0,170 mol/L
Knowing = 0,130 mol/L you can obtain:
0,210 mol/L = <em>(1)</em>
The 0,130 mol/L of Na⁺ comes from , thus:
0,130 mol/L = <em>(2)</em>
Replacing (2) in (1)
And:
The 0,050 M of NO₃⁻ comes from:
0,050M×0,250L× = <em>1,06 g of NaNO₃</em>
The 0,040 M of SO₄⁻ comes from:
0,040M×0,250L× = <em>1,42 g of Na₂SO₄</em>
<em></em>
