No there is no pH change
KCl+H20--> K2O + HCl
neither OH- or H+ is formed, which would make it either more acidic or more basic.

Does ammonia melt ice?
yes it does melt ice yes it does melt ice yes it does melt ice yes it does melt ice Please note that ammonia LOWERS the freezing point of water; at a certain (somewhat colder) temperature, the ammonia / water mixture will still freeze. ~ Ammonia mixed with water is NOT an example of a chemical reaction at all. NOT endothermic and NOT exothermic. WHY? A chemical reaction occurs when the chemicals you start with are different from the ones you end up with: not a state change, but an identity change. (from here on, substitute the word AMMONIA instead of KCl or potassium chloride; the text is borrowed from a similar answer with the same concept) -- After the KCl and water are mixed, you still have KCl and water. This is NOT a chemical reaction. Why does the temperature decrease? FREEZING POINT DEPRESSION and melting point elevation often occur when substances are mixed. In the situation described by the other respondent, the water immediately got colder when KCl was added. This is because the water was at its freezing/ melting point, in a cold room; when the water gets cold enough, it will all crystallize into a solid - frozen - crystalline matrix. BUT when the KCl (or salt, or any of a variety of substances) is added, this interferes with the crystallization process, so that more heat energy must be lost in order for the molecules to lock into their crystalline matrix. THEREFORE in that particular situation, the water was first mostly frozen with some liquid areas remaining at a low temperature...then KCl was added, and the crystals were broken apart, more able to release heat/ vibrate until a new freezing point, colder than before, is reached. Research freezing point depression for more information.
What release hydroxide ions when it dissolves in water?
Any type of base that has one or more OH- ions in it and is soluble in water will release hydroxide ions in aqueous solution. Example:NaOH + H20 --> Na+ + OH-
Is potassium chloride the same as magnesium chloride?
No, not in any way. Potassium chloride is KCl and Magnesium chloride is MgCl2 KCl is used as fertilizers and MgCl2 is used as a highway anti-icer. The only thing they share is Cl in their compound.
What kind of solid is KCl?
An ionically bonded salt.
How you prepare 0.02 M KCl solution?
I'll straightly go to the equation. KCL molar mass is 74.5513 g/mol. To prepare 0.02 M KCL solution, *0.02 M is also known as 0.02 mol/litre. 74.5513 g/mol x 0.02 mol/litre x 1 litre = 1.4910 g *note that in the equation we can cancel the mol and litre leave out the gram alone. So we need only 1.4910 g of KCL in 1 litre. You can change the volume, depend on your convenience but must in litre unit.
Is adding water to lemonade physical or chemical change?
Physical because, the lemonade dissolves into the water, without creating any of the chemical changing results.
What dissolves toothpaste besides water?
Any liquid will have the same effect on toothpaste as water.
What dissolves quicker in water?
Any ionic salts dissolves in water quickly.(Like NaCl, Sodium Chloride) as water is a polar solvent. The salt ionizes in water quickly than sugar.
How does methanol dissolve in water?
Yes it dissolves in water (any amount), it is rather called: homogeneously mixable with water
How does water become saline?
When it dissolves any salts or sugars it becomes salinated.
What ions would you find when an base dissolves in water?
A base is any substance that forms hydroxide ions in water.
Is known as the universal solvent because it dissolves more solutes than any other solvent?
Water.
What fibers do not dissolve in water?
Any chrisolite fiber obtained from mines and used in industries can not be dissolved in water.
Are there chemical agents lighter than air?

Does sugar absorb water?
It dissolves and dosn't have any side affects
A compound that releases a proton when it dissolves in water?
Any Arrhenius acid as HCl,HNO3, H2SO4 etc.
What has the ability to bond water to itself?
The cause is the formation of hydrogen bonds between water molecules.Any hydrophilic molecule that dissolves in water make H-bonding with water molecules
