CaBr2(aq) is an ionic compound which will have the releasing of 2 Br⁻ ions ions in water for every molecule of CaBr2 that dissolves.
CaBr2(s) --> Ca+(aq) + 2 Br⁻(aq)
            [Br⁻] = 0.17 mol CaBr2/1L × 2 mol Br⁻ / 1 mol CaBr2 = 0.34 M
The answer to this question is [Br⁻] = 0.34 M

A neutralization reaction is a _________ replacement reaction that starts with an ________ and a __________ and ends with ______
Alexeev081 [22]

Answer:

Double, acid, base, water, salt.

Explanation:

The general reaction of a neutralization is:

X(OH) + YH → H₂O + XY

If you see, the reaction is a <em>double replacement reaction </em>because the cation and the anion of the two reactants switch places, forming two new compounds or products.

Always, the reaction starts with an <em>acid </em>and a <em>base </em>and will produce <em>water </em>and a <em>salt. </em>

I hope it helps!
