So the question still remains â what age is the right age? Unfortunately, thereâs no cut-and-dry answer. Family circumstances, a childâs maturity level and the real need for a cell phone all contribute to when the right time is.
Discovered in 1967, acesulfame potassium (also called acesulfame K or ace-K) is a no-calorie sweetener approximately 200 times sweeter than table sugar (sucrose). It has a clean, quickly perceptible sweet taste and excellent stability under high temperatures and good solubility.
For example, addition of potassium permanganate to an aqueous solution of sugar and sodium hydroxide produces the chemical chameleon reaction, which involves dramatic color changes associated with the various oxidation states of manganese. A related vigorous reaction is exploited as a fire starter in survival kits.Using sodium hydroxide the end product is not sodium manganate but an Mn(V) compound which is one reason the potassium permanganate is more commonly used than sodium permanganate. Furthermore the potassium salt crystallizes better).
