When a positive ion of a base combines with a negative ion, they form an ionic compound called a salt. This reaction is known as neutralization and results in the formation of water molecules. The salt produced depends on the specific base and negative ion involved in the reaction.

What type of ionic compound does the positive ion of a base and the negative ion of an acid combine to form?
When the positive ion of a base combines with the negative ion of an acid, they form a salt compound. The positive ion from the base combines with the negative ion from the acid through an ionic bond to create a neutral compound known as a salt.
Positive ions from a base and negative ions from an acid form a what?
A salt
What happens when you mix an acid with a hydroxide base?
When an acid is mixed with a hydroxide base, a neutralization reaction occurs resulting in the formation of water and a salt. The hydrogen ions from the acid combine with the hydroxide ions from the base to form water, while the positive and negative ions from the acid and base combine to form a salt.
Is chloride a positive or negative ion?
Chloride is a negatively charged ion, written as Cl-. It is the conjugate base of hydrochloric acid (HCl) and carries a negative charge due to the extra electron it possesses.
What chemical reaction in which and acid combines with a base what is called?
The chemical reaction in which an acid combines with a base is called a neutralization reaction. In this reaction, the acid and base react to form water and a salt.
What type of ionic compound does the positive ion of a base and the negative ion of an acid combine to form?
When the positive ion of a base combines with the negative ion of an acid, they form a salt compound. The positive ion from the base combines with the negative ion from the acid through an ionic bond to create a neutral compound known as a salt.
How do you predict whether a power will be negative or positive?
To predict whether a power will be negative or positive, examine the base and the exponent. If the base is positive, any exponent—whether positive or negative—will yield a positive result. Conversely, if the base is negative, an even exponent results in a positive value, while an odd exponent produces a negative value. Thus, the sign of the power depends on both the sign of the base and whether the exponent is odd or even.
How do you change a negative exponents to positive?
To change a negative exponent to a positive one, you take the reciprocal of the base raised to the positive exponent. For example, ( a^{-n} ) can be rewritten as ( \frac{1}{a^n} ), where ( a ) is the base and ( n ) is the positive exponent. This rule applies to any non-zero base.
How do you make a negative exponent positive?
You can do it if you replace the base by its reciprocal.
How is a negative integer power on a base related to the corresponding positive integer power on that base?
A negative integer power of a base is the reciprocal of the base raised to the corresponding positive integer power. For example, ( a^{-n} = \frac{1}{a^n} ), where ( a ) is the base and ( n ) is a positive integer. This relationship shows that as the exponent decreases into the negatives, the value of the expression represents a division by the base raised to the positive power.
When rewriting an exponential expression with a negative exponent and a positive base to an expression containing only a positive exponent does the sign of the base change?
No.
What is formed from a positive ion base and a negative ion from an acid?
A salt
Can a exponential functions be a negative number?
Exponential functions of the form ( f(x) = a \cdot b^x ), where ( a ) is a constant and ( b ) is a positive base, cannot yield negative values if ( a ) is positive. However, if ( a ) is negative, the function can take on negative values for certain inputs. In general, exponential functions are always positive when ( a ) is positive and ( b ) is greater than zero, but they can be negative if ( a ) is negative.
Why you use negative source in emitter biasing?
to get the base- emitter junction forward bias we should connect the negative of the diode with the negative of the battery and the positive of the diode with the positive of the diode so we should connect negative source in the emitter
What is a ionic compound formed from the negative ions of and acid and the positive ions of a base?
salt
How do you change negative powers to positive?
You take away the negative sign and put 1 over the base with the (now positive) exponent. Example: x to the negative 2 becomes 1 over x to the 2nd.
Why negative numbers don't have logarithim?
The logarithmic function is not defined for zero or negative numbers. Logarithms are the inverse of the exponential function for a positive base. Any exponent of a positive base must be positive. So the range of any exponential function is the positive real line. Consequently the domain of the the inverse function - the logarithm - is the positive real line. That is, logarithms are not defined for zero or negative numbers. (Wait until you get to complex analysis, though!)
