A reputable research company Kantar recently revealed that Android users in Europe now favors iOS. A huge number of those android users are now siding with iOS and the iPhone.
The interesting thing is this movement from Google’s operating system is actually happening during the summer, a season of year where Apple’s sales usually drop because consumers are awaiting a new iPhone to launch in September
In the biggest economies in Europe (Spain, France, Germany, Italy, and the United Kingdom) saw a combined 27% of all people who purchased a smartphone during the last quarter came from Android to iOS. Even in the United States the number was 9% showing Apple’s strategies are paying off.
This is especially the case in Europe though where Apple and the iPhone are enjoy even more success. Even Samsung is running scared on the Old Continent as the company decided not to launch the Galaxy Note 5 in Europe, allowing the iPhone 6 Plus to thrive.

Solutions and Solubility
CHEMISTRY OF SOLUTIONS
A solution is a - mixture of 2 or more substances in a single phase. One constituent is usually regarded as the SOLVENT and the others as SOLUTES.
Solutions are homogeneous mixtures of two or more pure substances.
In a solution, the solute is dispersed uniformly throughout the solvent
PARTS OF A SOLUTION
SOLUTE – the part of a solution that is being dissolved (usually the lesser amount
SOLVENT – the part of a solution that dissolves the solute (usually the greater amount)
Solute + Solvent = Solution
KINDS OF SOLUTION
Dilute - small amount of solute dispersed in the solvent
Concentrated - large amount of solute is dissolved in the solvent
Types of Solutions Based on Solute Concentration
- Hypotonic solutions - (lower solute concentration) to the solution
- Hypertonic solutions- (higher solute concentration) to the solution
- Isotonic solutions - are equal in their solute concentrations. We say that they are isotonic to each other.
SOLUBILITY
Solubility - refers to the maximum amount of solute, expressed in grams, that can be dissolved in 100 g of water at a specific temperature & pressure.
Solubility = Gram of solute
100 g of Water
Soluble - a substance that dissolves in a solvent
Insoluble - a substance that does not dissolve in a solvent (sand is insoluble in water)
Slightly Soluble - a material will be sparingly soluble if the amount which can be dissolved in 100ml of solute ranges between 0.1g to 1g.
SOLUBILITY IN WATER
Immiscible - two liquids that are insoluble (Oil & Vinegar)
Miscible - two liquids that are soluble in each other (Water & Alcohol ; Water & Antifreeze)
Slightly / Partly Miscible – two liquids are slightly soluble ( Water & Ether ; Alcohol & Oil )
Degree of Saturation
Saturated solution
- Solvent holds as much solute as is possible at that temperature.
- Undissolved solid remains in flask.
- Dissolved solute is in dynamic equilibrium with solid solute particles.
- Contains the maximum amount of solute dissolved.
NaCl = 36.0 g/100 mL water
Unsaturated Solution
- Less than the maximum amount of solute for that temperature is dissolved in the solvent.
- No solid remains in flask.
- Can still dissolve more solute (for example 28.0 grams of NaCl/100 mL)
Supersaturated
- Solvent holds more solute than is normally possible at that temperature.
These solutions are unstable; crystallization can often be stimulated by adding a “seed crystal” or scratching the side of the flask
