when base react with water it decomposes to give hydroxide OH negative and acids react with water to produce hydronium ion H3O positive.......
Neither. No substance on its own on is an ion. Nitric acid is electrically neutral. When dissolved in water, nitric acid breaks apart, releasing both positive hydronium ions and negative nitrate ions.
Hydronium Ions
Yes.
A hydronium ion is considered polar. You can determine its polarity by looking at the electronegativity of the atoms. Hydrogen is positive, and oxygen is negative.
Positive + Negative = Negative Negative + Negative = Positive Positive + Positive = Positive Negative + Positive = Negative
Negative * positive = negative Positive * positive = positive Negative * negative = positive
The pH of a solution can be less than zero. Remember that pH is defined as the negative logarithm of the hydronium ion concentration, pH = -log[H3O+]. For pH to be negative, the log of the hydronium ion concentration needs to be positive. The log of a number is only positive if that number is greater than one. For example, the value of log(2) is about 0.30. This means that the pH of a strong acid that has a concentration of greater than 1 molar will be negative.
The rules for the sign (positive or negative) of the result of a multiplication is the same as division. For multiplication: Positive * Positive --> Positive Positive * Negative --> Negative Negative * Positive --> Negative Negative * Negative --> Positive For division: Positive / Positive --> Positive Positive / Negative --> Negative Negative / Positive --> Negative Negative / Negative --> Positive
Yes. Negative/negative = positive Postive/Positive = positive Negative/Positive - negative
Negative * positive = negative Positive * positive = positive Negative * negative = positive
A negative divided by a positive is negative. A negative divided by a negative is positive. A positive divided by a positive is positive. A positive divided by a negative is negative.
