The scientific method is defined as a method of research in which a problem is identified, relevant data is gathered, a hypothesis is formulated from this data, and the hypothesis is empirically tested.
Answer:
c) a buffer solution with pH= 5
Explanation:
The equation of hydrolisis of water is:
1x10⁻¹⁴ = [H⁺] [OH⁻]
That means if we know [H⁺] we can find hydroxide-ion concentration and vice versa.
a) HCl 0.1M = [H⁺] = 0.1M;
1x10⁻¹⁴ / [H⁺]
1x10⁻¹⁴/ 0.1M = [OH⁻]
1x10⁻¹³M = [OH⁻] hydroxide- ion concentration.
b) 0.1M H₂SO₄ = 0.2M [H⁺]
1x10⁻¹⁴/ 0.2M = [OH⁻]
5x10⁻¹⁴M = [OH⁻]
c) pH = 5.
[H⁺] = 1x10⁻⁵M
1x10⁻¹⁴/ 1x10⁻⁵M = [OH⁻]
1x10⁻⁹M = [OH⁻]
d) pOH = 12.
[OH⁻] = 1x10⁻¹²M
That means risht answer is:
<h3>c) a buffer solution with pH= 5</h3>
I think it's just water right..?
Answer:
positive charge comes from having more protons than electrons; negative charge comes from having more electrons than protons charge is quantized, meaning that charge comes in integer multiples of the elementary charge e
