Answer:
Qualitative
Explanation:
I'm not sure if there was another part to the question, but if you are looking at the color of the sand, that is a qualitative observation.
- Quantitative statements involve numbers. (Ex: The house has 4 bedrooms.)
- Qualitative statements describe characteristics. (Ex: The house is blue.)
2LiOH + H₂SO₄ = Li₂SO₄ + 2H₂O
v(H₂SO₄)=0.025 L
v(LiOH)=0.0836 L
c(LiOH)=0.12 mol/L
n(LiOH)=v(LiOH)c(LiOH)
n(H₂SO₄)=n(LiOH)/2=v(LiOH)c(LiOH)/2
c(H₂SO₄)=n(H₂SO₄)/v(H₂SO₄)=v(LiOH)c(LiOH)/(2v(H₂SO₄))
c(H₂SO₄)=0.0836*0.12/(2*0.025)=0.20064 mol/L
≈0.20 M
