To determine the expected pH of the resulting solution of the following substances, create a balanced chemical equation of their ionization in water:
HI
HI + H2O ---> H+ + I-
It completely dissociates into H+ and I-. Due to the presence of the Hydronium Ion, the solution is acidic.
KBr
KBr + H2O ----> HBr + KOH
The salt KBr is formed by a strong base and a weak acid, therefore, the solution it forms with water is basic.
LiOH
LiOH + H2O ----> Li+ + OH-
It dissociates completely in water, turns into Li+ and OH-. Due to the presence of Hydroxide Ion, the solution becomes basic.
Answer:
Concentrated sulfuric acid can perform a dehydration reaction with table sugar. After mixing, the color changes from white to brownish and eventually to black. The expansion of the mixture is the result of vaporization of water and CO2 inside the container.

<span>Chemical change would be happening. Colorless is a physical property on its own, Determining change to requirements you have to compare two things. Is this a physical property or is this a Chemical change and color in itself would represent a change in chemical properties to the aqueous salt solutions.</span>
<u>Answer:</u> The density of sugar is 
<u>Explanation:</u>
To calculate the density of a substance, we use the equation:
We are given:
Mass of sugar = 316 g
Volume of box = 
Putting values in above equation, we get:
Hence, the density of sugar is
